Abstract

A coil component that can be made thinner while ensuring sufficient magnetic characteristics includes a magnetic part, a conductor part, and multiple insulator parts. The magnetic part is constituted by magnetic alloy grains. The conductor part has multiple winding parts and is wound around one axis inside the magnetic part. The multiple insulator parts are each placed between the multiple winding parts, each having a winding shape that includes two joining surfaces that are respectively joined to two winding parts facing each other at least partially in the direction of the one axis, and are each constituted by electrically insulating grains.
