Abstract: A coil component including an element assembly and a coil conductor embedded in the element assembly. The element assembly includes a first magnetic layer and a second magnetic layer that constitute a first principal surface and a second principal surface, respectively, where the first principal surface and the second principal surface are opposite to each other in the element assembly. The first magnetic layer has a higher relative magnetic permeability than the second magnetic layer. At least part of a winding portion of the coil conductor is located in the first magnetic layer. The first magnetic layer contains metal magnetic particles and a resin, and the second magnetic layer contains metal magnetic particles, a resin, and zinc oxide particles. The metal magnetic particles and the zinc oxide particles are dispersed in the resin.

Abstract: An inductor component includes an element body, a coil, and a first outer electrode and a second outer electrode, in which the coil includes a coil wiring, a first extended wiring, and a second extended wiring. The first extended wiring includes a first connection surface connected to the coil wiring and a second connection surface connected to the first outer electrode, and a first straight line connecting the first connection surface and the second connection surface is inclined to the direction orthogonal to the first main surface.
