PURPOSE:To improve the mechanical strength of an inductance element by winding a necessary coil on a bobbin to connect the ends to outer terminals secured to the bobbin, and sealing the coil with sheath resin mixed with magnetic powder, thereby rigidly holding the outer terminals. CONSTITUTION:Coils 11 of numbers of turns and outputs as required are wound on a bobbin 11, the ends 11a, 11b of the coil are connected to outer terminals 13, 14 protruding from a bobbin 10, and the whole bobbin 10 containing the connecting parts of the ends 11a, 11b is sealed with sheath resin 12 mixed with magnetic powder. Since the coil 11 is wound on the bobbin 10, the coil 11 can be formed with necessary numbers of turns and outputs by altering the diameter of the conductor in response to the utility of various specifications, and terminal pins 13, 14 are held by the resin 12, thereby enhancing the mechanical strength.
