Abstract
An inductance element of the type that includes a coil bobbin having flanges at the ends thereof, a pair of pot cores engaging the bobbin, and a fastening member for fastening together the pot cores and bobbin. At least one of the bobbin flanges includes a joining part that extends outwardly from the bobbin flange and engages both the adjacent one of the pot cores and the fastening member to prevent relative rotation of the bobbin and adjacent pot core and fastening member. One of the bobbin flanges may include a stepped part having pins extending therefrom for making electrical connection to the inductance element. The stepped part is spaced from the bobbin flange, and connection wires may extend within the space.
