Abstract: An electronic component includes a body containing glass, external conductors including a first external electrode and a second external electrode each disposed on an external surface of the body, a spiral conductor within the body, and extended conductors including a first extended conductor and a second extended conductor each disposed within the body. One end portion of the spiral conductor is electrically connected to the first external electrode with the first extended conductor therebetween and another end portion is electrically connected to the second external electrode with the second extended conductor therebetween. The spiral conductor contains Ag and at least one oxide selected from the group consisting of Al2O3, SiO2, ZnO, TiO2, and ZrO2, and the extended conductor contains Ag, but none of Al2O3, SiO2, ZnO, TiO2, and ZrO2.

Abstract: A common-mode choke coil includes a multilayer body, a first coil, and a second coil. The multilayer body includes plural stacked non-conductor layers. The first and second coils are incorporated in the multilayer body. The first coil includes a first coil conductor. The second coil includes a second coil conductor disposed along an interface between non-conductor layers different from an interface between non-conductor layers along which the first coil conductor is disposed. With the first coil conductor and the second coil conductor being viewed in plan in the stacking direction of the multilayer body, the first coil conductor and the second coil conductor have no portion where the two coil conductors overlap each other, except for a portion where the two coil conductors cross each other.

Abstract: A multilayer coil component includes an element body formed by stacking a plurality of insulating layers on top of one another, a coil buried inside the element body, and an outer electrode that is electrically connected to the coil. The dead weight of the multilayer coil component lies in a range from 0.2 mg to 0.35 mg. The element body has a mounting surface and has a coil lead-out surface to which the coil is electrically led out and on which the outer electrode is provided. Looking at a cross section of the element body that is perpendicular to the mounting surface and the coil lead-out surface, a radius of curvature of an edge portion where the mounting surface and the coil lead-out surface intersect lies in a range from 13 μm to 30 μm.

Abstract: A common-mode choke coil includes a multilayer body, a first coil, and a second coil. The multilayer body is a cuboid in shape that includes plural stacked non-conductor layers. The first and second coils are incorporated in the multilayer body. The first coil includes a first coil conductor, and the second coil includes a second coil conductor. The first coil conductor is positioned with gaps SG1 to SG4 interposed between the first coil conductor and the outer periphery surface of the multilayer body. The second coil conductor is positioned with gaps SG5 to SG8 interposed between the second coil conductor and the outer periphery surface of the multilayer body. Of the four absolute values of the differences between the gaps SG1 to SG4 and the corresponding gaps SG5 to SG8, at least two absolute values are greater than or equal to 0.02 mm.
