ABSTRACT:
In A method of manufacturing a solid inductor having an inner conductor formed by passing through a magnetic, material. A vitreous diffused material is applied to the surface of the magnetic material, and the diffused material is diffused into the magnetic material by heat treatment, to form a diffusion layer exhibiting low permeability. The thickness of this diffusion layer is adjusted, thereby to make it possible to adjust the inductance value of the solid inductor as well as to improve resistance to humidity of the solid inductor.
