PROBLEM TO BE SOLVED: To easily adjust the current-inductance characteristic of a choke coil for a power rectifying circuit. SOLUTION: An E-shaped core 2, having side leg sections 2b and 2c on both sides of a central leg section 2a, is butted against an I-shaped core 1. The edge of one end section of the core 1 is directly abutted against the end face of one side leg section 2c and the core 1 is abutted against the end faces of the central leg section 2a and the remaining side leg section 2b via different magnetic materials 10 and 11.
