摘要： An electrostatic protection component includes: a body in which a plurality of ceramic substrates is laminated; and a pair of discharge electrodes which are formed within the body and which are spaced to face each other. The discharge electrodes include main body portions extending along a longitudinal direction, and the main body portions include tips in the longitudinal direction and side edges extending along the longitudinal direction. The pair of discharge electrodes are arranged such that both the main body portions are adjacent to each other in a short direction. The discharge electrodes face each other in the short direction between the side edges, and discharge occurs only between the side edges, between the discharge electrodes.

摘要： A second coil opposes a first coil in a first direction. The first and second coils are positioned between a first conductor and a second conductor in the first direction. The first conductor is adjacent to the first coil in the first direction and overlaps a part of the first coil when viewed from the first direction. The second conductor is adjacent to the second coil in the first direction and overlaps a part of the second coil when viewed from the first direction. The first and second conductors are of a shape extending in a line. Inner regions of the first and second coils include regions not overlapping the first and second conductors when viewed from the first direction.

摘要： A first coil is configured in such a structure that first and second coil conductors are connected by a first through-hole conductor. A second coil is configured in such a structure that third and fourth coil conductors are connected by a second through-hole conductor. The first and second coils are arranged in a nonmagnetic section consisting of nonmagnetic layers. A portion located inside the first coil and the second coil in the nonmagnetic section includes a first regional portion and a second regional portion adjacent to each other when viewed from a laminated direction of the nonmagnetic layers. The first and second through-hole conductors are located in the first regional portion so as to be adjacent to each other, when viewed from the laminated direction. A magnetic core section comprised of a magnetic material is located in the second regional portion when viewed from the laminated direction.
