ABSTRACT:
A coil component includes a first coil winding wound around a first axis, a second coil winding wound around a second axis and juxtaposed to the first coil winding, a connecting member for electrically connecting second terminals that are one end of the first coil winding and one end of the second coil winding, and a heat conductive member mounted on the connecting member and having electrical insulation properties and heat conductivity. The first and second coil windings are each wound such that magnetic flux is generated by a current flowing through the first and second coil windings to pass through an opening of the first coil winding and through an opening of the second coil winding in an opposite direction to the direction passing the opening of the first coil winding. Accordingly, heat generated in the first and second coil windings is dissipated from the heat conductive member.
