Abstract
A coil component includes a plurality of conductor layers constituted of a first conductor layer to a fourth conductor layer that includes a function layer and a coil layer wound around an axis center; and a covering portion that is formed of an insulative resin, integrally covers the plurality of conductor layers, and is interposed between conductor layers adjacent to each other. The coil layer and the function layer of the plurality of conductor layers have substantially the same shape in a plan view. The fourth conductor layer has a connection conductor layer connecting the coil layer and the function layer to each other. A conductor layer having no connection conductor layer among the plurality of conductor layers has a protrusion portion corresponding to the connection conductor layer at a position overlapping the connection conductor layer in a plan view.
