Abstract
A coil component includes an element and a coil that is provided inside the element and that is spirally wound. The coil includes a plurality of coil conductor layers and an extended conductor layer, which are laminated in a first direction. The extended conductor layer overlaps a side gap portion, which is situated on an outer side of a region of the element that is surrounded by the coil conductor layers, and extends so as to reach an outer surface of the element. The element includes a first stress relaxation layer that contacts the coil conductor layers, and a second stress relaxation layer that, while extending along the extended conductor layer, contacts a coil-conductor-layer side of the extended conductor layer, and is positioned inside the side gap portion without reaching the outer surface of the element.
