Abstract
A coil component has a first coil part and a second coil part, a middle member, and a shield member. Each of the first and second coil parts includes a drum core and a winding. The middle member is located between the first and second coil parts arranged in a state in which axes of winding drums in the respective first and second coil parts are parallel to each other. The shield member is formed at least in part of an outside surface of the winding in each of the first and second coil parts and is a resin containing a magnetic material powder. The magnetic permeability of the middle member is lower than that of the core and the shield member.
