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 material that contains resin, and whose insulation property is higher than that of the first resin part; a coil embedded in 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; wherein covered parts of the leader parts, which are covered with the insulating film, are embedded partially in the second resin part, and the second resin part is disposed between the terminal parts and the first resin part, thereby preventing shorting between the terminal parts.
