PROBLEM TO BE SOLVED: To enable miniaturization of an inductance element and to improve insulation of a core for a conductive coil. SOLUTION: A coil 3 is wound around a bobbin 5, an I-shaped core 2 of magnetic material with low resistivity is inserted into a hollow hole of the bobbin 5, and a core 1 of magnetic material having a shape like a numeral 8 with high resistivity is set vertically on the upper surface of the bobbin 5. The core 1 is opposed to the I-shaped core 2 at three parts, i.e., space part 5a dividing the coil winding of the bobbin 5, and both the edge parts of the I-shaped core 2 to form a double-8 like core as an inductance element. |
