Abstract: A coil device includes a coil portion and a bobbin. The coil portion includes wires connectable to terminals. The bobbin includes a first terminal block and a second terminal block formed on both sides in a winding axis direction of a cylindrical portion for forming the coil portion around the cylindrical portion. A length of the first terminal block in a width direction perpendicular to the winding axis direction is larger than that of the second terminal block in the width direction.

Abstract: A coil device includes a bobbin, a first winding part, and a second winding part. A partition portion is formed on an outer peripheral surface of the bobbin. The first winding part is wound around the outer peripheral surface at one side of the partition portion. The second winding part is wound around the outer peripheral surface at the other side of the partition portion and has an inner winding layer and an outer winding layer located farther to the outer peripheral surface at the other side than the inner winding layer.
