Abstract
A coil component includes: a substrate body having a first resin part formed by a resin that contains magnetic grains, and a second resin part joined to the surface of the first resin part and formed by a resin that contains filler, and whose resin content is higher than that of the first resin part; a coil embedded at least in a part of the first resin part and formed by a conductor having an insulating film; leader parts formed by the conductor and led out from the coil to the second resin part; and terminal parts connected electrically to the leader parts and provided in the second resin part. The above structures can enhance mechanical strength.
