Abstract: A coil device has a wound portion, a leadout portion led out from the wound portion, a terminal including a wire connecting portion connected to the leadout portion, and an element body covering the wound portion, the leadout portion and the wire connecting portion. A winding axis of the wound portion is perpendicular to a mounting facing surface of the element body. The leadout portion has a bent portion bent so as to protrude inward when viewed along the winding axis, and an inner angle of the bent portion is an obtuse angle.

Abstract: A coil device has a wound portion, a leadout portion led out from the wound portion in a first direction, and an element body covering the wound portion and the leadout portion. A winding axis of the wound portion is perpendicular to a mounting facing surface of the element body and is displaced to a second direction opposite to the first direction with respect to a center of the element body. An outer circumferential surface of the wound portion is distorted so as to bulge outward in the first direction from the outer circumferential surface of the wound portion.
