An insulation rib for reinforcing the intensity of a flange unit is formed on the outer side of the flange unit of the bobbin unit. The bobbin unit is comprised of a tubular body unit, a flange unit, and a plurality of bobbins with an external connection terminal. A core(40) is inserted into a through hole of the bobbin to form a magnetic path. A coil unit(50) includes a coil wound around the plurality of bobbins.
