PROBLEM TO BE SOLVED: To provide a drum-type and small inductor which satisfies a high inductance and a low resistance at the same time and to provide its manufacturing method. SOLUTION: The inductor is formed by applying a magnetic resin 2 which is a homogeneous mixture of a magnetic powder 5 and a resin 6 at a constant compounding ratio for covering the periphery 1a of a coil 3 and lateral flange peripheries 1b and the flange surface 1c of a drum core 1 when needed. Also, the magnetic resin 2 is dried and hardened while permanent magnets 4 are arranged on one or both flange surfaces 1c of the drum core 1. COPYRIGHT: (C)2009,JPO&INPIT
