摘要： An inductance device comprises a drum core having a center core, and flanges integrated therewith. The center core is wound with a wire, whereas a magnetic gap is formed between the upper flange and lower flange. The magnetic gap is closed with an insulator, mixed with a magnetic substance, having rubber elasticity. The insulator comprises an overhang and an insertion integrally formed therewith. The overhang presses a region in the upper flange so as to hang from this region. The insertion tightly fits into the magnetic gap.
