Abstract

A composite magnetic material is provided that includes a resin and first magnetic particles provided inside the resin. Each of the first magnetic particles includes a first core comprising a metal magnetic material, and an insulating film that covers the first core. The first core has a substantially flat shape having a short axis and a long axis. A thickness of the insulating film in the long axis direction of the first core is smaller than a thickness of the insulating film in the short axis direction of the first core. In addition, a coil component is provided that includes the composite magnetic material in an element body of the coil component.
