METHOD FOR MANUFACTURING INDUCTANCE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for easily manufacturing a small and light inductance element by saving a space without winding a wire or forming a conductive pattern on a printed wiring board. SOLUTION: A lower side lead frame 6 where a plurality of patterns 5 are radially formed is overlapped with an upper side lead frame 7 where a plurality of patterns 15 are radially formed. The pattern 15 bonds one end (one end part 5A) on the center side of the pattern 5 and the other end (bonding part 8) on the outer peripheral side of the other pattern adjacent to the pattern 5. The patterns 5 and 15 form a winding part 1 in a toroidal shape by cutting it near the outer side of the other end of the pattern 5. COPYRIGHT: (C)2004,JPO&NCIPI
