Title:
INDUCTANCE ELEMENT
Document Type and Number:
Japanese Patent JPS58137206
Kind Code:
A
Abstract:
PURPOSE: To eliminate the winding process and to greatly reduce a thickness by a construction wherein a zig-zag conductive pattern is separated by cut-outs into plural parts which are arranged on the upper and lower sides alternately with respect to a plane.
CONSTITUTION: A zig-zag pattern 27 is formed with a copper foil 26 on a flexible board 25. Terminals 28, 29 are led out from both ends of the pattern 27. Then, the board 25 is separated by plural cut-outs into upper and lower parts alternately. A flat core 31 formed of ferrite, etc. is inserted to a space defined by those alternate upper and lower parts. Thus, the core 31 assumes such a state that conductive wires are wound around it.
