Abstract
A coil component includes a base body, a conductor inside the base body, and an external electrode electrically connected to the conductor. The base body has metal magnetic particles bonded by a first resin, and has a first surface that faces a mounting board, and a second surface adjacent to the first surface. The external electrode includes a first conductive resin layer on the first surface, which is made of a material that contains a second resin and first metal particles. The external electrode includes a second conductive resin layer on the second surface, which is made of a material that contains a third resin and second metal particles. A content rate of the third resin is smaller than a content rate of the second resin. The external electrode includes a metal layer covering the first and second conductive resin layers.
