Abstract
Disclosed herein is a coil component that includes: a core including a winding core part extending in a first direction and a flange part provided at one end of the winding core part in the first direction, the flange part having a first surface substantially parallel with the first direction; a plate-like member fixed to the first surface of flange part; and a wire wound around the winding core part. The first surface of flange part has a cut part greater in size than a diameter of the wire.
