摘要： A spark plug 100 comprised of a metal shell 1, an insulator 2, a center electrode 3 and a ground electrode 4. A rear-end face of the ground electrode 4 is welded to a front-end face of the metal shell 1, and a bent portion 5 located at the intermediated position in the longitudinal direction is bent toward the center of the spark plug 100. The ground electrode 4 assumes a circular-shape with a diameter of 2 mm or less whereby an inflow of an air-fuel mixture is not disturbed even when the air-fuel mixture directly flows into a back face of the ground electrode 4. The ground electrode 4 is comprised of an outer layer 4A made of a nickel alloy and an inner layer 4B made of pure copper with an excellent thermal conductivity, in which a ratio of a cross-sectional area of the inner layer 4B to the entire cross-sectional area of the ground electrode 4 is 10% or more to 35% or less. Thus, the spark plug 100 which is excellent in heat sinking ability and can prevent a spring back phenomenon due to a difference in a coefficient of thermal expansion.

摘要： The present invention provides a liquid crystal display device with high image visibility at low power consumption and produced at low cost by using an interlayer dielectric film, which has low dielectric constant, high heat-resistant property, high optical transmissivity, high film thickness and high flattening property produced at low cost. An organic siloxane dielectric film is used as an interlayer dielectric film of the liquid crystal display device. A ratio of nitrogen content to silicon content (Ni content/Si content) in the interlayer dielectric film is controlled to 0.04 or more in the element ratio. The limiting film thickness to suppress and limit the cracking caused by the thickening of the interlayer dielectric film is set to 1.5 μm or more.
