Abstract
Disclosed herein is a coil component that includes a core including a winding core part extending in the x-direction and a flange part, a terminal electrode provided on the flange part, and a wire wound around the winding core part and connected to the terminal electrode. The terminal electrode does not overlap the winding core part in the y-direction. The wire includes a wound part wound around the winding core part and a drawn part drawn from the wound part, running across the winding core part in the z-direction and connected to the terminal electrode. The core has a positioning part that positions the drawn part of the wire in the y-direction.
