PROBLEM TO BE SOLVED: To provide a fixed inductor which is small-sized, made lightweight and obtaining stable inductance and appropriate DC superimposing characteristics by providing a proper air gap. SOLUTION: A fixed inductor comprises a stick-like core 1, a coil 5 winding an insulating coating electrical wire 2 around the stick-like core 1, and an angular sleeve core 3 for housing the coil 5 therein. The inductor is mechanically provided with an air gap G by providing recessed portions 1a or projecting portions on both end faces of the stick-like core 1. COPYRIGHT: (C)2006,JPO&NCIPI
