Abstract
Disclosed is a method of manufacturing an electromagnetic member having properties of magnetic anisotropy as well as electrical conductivity, comprising the steps of coating an outer circumferential surface of each of a plurality of magnetic strips with a first electrically conductive material to a predetermined thickness to thereby form a plurality of composite magnetic strips, binding the plurality of composite magnetic strips, and filling spaces among the plurality of composite magnetic strips in the bundle with a second electrically conductive material substantially the same as the first electrically conductive material. By this method, a mechanically strong electromagnetic member can be obtained in which adjusting the thickness of the first electrically conductive material, the ratio between the magnetic property and the electrically conductive property can be easily adjusted by adjusting the thickness of the first electrically conductive material and blow-holes can be prevented from being generated.
