摘要： An ignition apparatus includes a spark plug and an ignition coil. The spark plug has a plug terminal protruding proximalward from an insulator. The ignition coil includes a coil main body, which includes a primary coil and a secondary coil, and a helical spring that electrically connects the secondary coil and the plug terminal. The plug terminal is made of a material that is both electrically conductive and magnetic. The plug terminal includes a terminal main body, which has an outer diameter greater than an inner diameter of the spring, and a terminal extension portion that has an outer diameter less than the inner diameter of the spring and extends proximalward from the terminal main body. A distal end portion of the spring abuts the terminal main body. The terminal extension portion is inserted and arranged in the spring. Between an outer circumferential surface of the terminal extension portion and an inner circumferential surface of the spring, there is interposed an insulating member.

摘要： To provide an ignition plug having low power loss even though iron is a main component of a center electrode thereof, to which a high frequency power such as a microwave is electrically supplied. A low impedance layer 6 composed of a material having magnetic permeability lower than iron is provided between an outer peripheral surface of a center electrode 2 and an inner peripheral surface of an axial hole 30 of an insulator 3. The low impedance layer 6 is in contact with at least the outer peripheral surface (surface) of the center electrode 2, thereby reducing power loss of an electromagnetic wave flowing on the surface of the center electrode 2. More particularly, the low impedance layer 6 is made of silver, copper, gold, aluminum, tungsten, molybdenum, titanium, zirconium, niobium, tantalum, bismuth, palladium, lead, tin, an alloy composed mainly of these metals, or a composite material of these metals.

摘要： A connection device for connecting a first power supply and a second power supply to an ignition plug has a first power supply side line which establishes electrical connection between the ignition plug and the first power supply and which is electrically connected to the second power supply, and a second power supply side line which establishes electrical connection between the ignition plug and the second power supply. The first power supply side line includes a first diode which prevents a current inflow from the second power supply into the first power supply or a current inflow from the first power supply into the second power supply, and an inductor disposed between the first diode and the ignition plug. The inductor is disposed around the second power supply side line while being separated from the second power supply side line. Thus, noise can be suppressed.

摘要： An adhesion of a nickel plating layer to a metal shell is improved, and an effect of improving a corrosion resistance by providing the nickel plating layer is sufficiently exerted. A spark plug 1 includes a cylindrical metal shell 3 that extends in an axial CL1 direction, and a nickel plating layer 31 that is made of metal containing nickel as a main component and covers an outer surface of the metal shell. In a monochrome image of 256 gradations where black is 0 and white is 255, which is obtained by observing a cross-section perpendicular to an outer surface of the nickel plating layer by a transmission electron microscope with an acceleration voltage of 200 kV, an average value in 256 gradations of the monochrome image is 170 or larger and 230 or smaller.

摘要： Provided is a spark plug which allows a predetermined resistance to be imparted to a resistor with restraint of variation in resistance of the resistor and in turn, enables enhancement of yield. The spark plug includes a ceramic insulator having an axial hole extending in the direction of an axis CL1, a center electrode, and a terminal electrode. A resistor is provided in the axial hole through sintering of a resistor composition which contains a conductive material such as carbon black, glass powder, and ceramic particles other than glass. As viewed on a section of the resistor taken along a direction orthogonal to the axis CL1, 50% or more of sintered glass powder formed through sintering of the glass powder has a circularity of 0.8 or greater.
