PROBLEM TO BE SOLVED: To provide an inductor which allows for formation of an efficient magnetic circuit for magnetic flux generated in the inner part of winding, without causing magnetic saturation of a magnetic core even under a large current, while suppressing generation of noise due to magnetic flux leakage to the outside.SOLUTION: A magnetic core is not arranged on the winding inside of a coil 2, at least one of a resin body 4 and a magnetic material 3 is arranged on the winding outside of the coil 2, and the winding outside of the coil is especially covered with at least one of the resin body and magnetic material.SELECTED DRAWING: Figure 1 |
