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 core body, a wire, and a plurality of terminals. The bobbin includes a pair of connection side portions and a pair of terminal tables. The pair of connection side portions is arranged near both sides of a winding core of the core body and wound by the wire along with the winding core. The pair of terminal tables is arranged on both ends of the connection side portions and respectively includes the terminal protruding outward in a winding axis of the winding core. The core body includes a pair of flanges arranged on both ends of the core body in the winding axis. Each of the terminal tables includes a flange storage recess configured to contain the flange.
