    Abstract: A coil component includes a core including a winding core portion, a first flange portion, and a second flange portion, a first wire and a second wire that are wound around the winding core portion in the same direction and that form a winding portion, a first terminal electrode and a second terminal electrode that are disposed on the first flange portion, and a third terminal electrode and a fourth terminal electrode that are disposed on the second flange portion. A length of the winding portion along a bottom surface of the winding core portion is shorter than a length of the winding portion along an upper surface of the winding core portion.
