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.
