PURPOSE:To enhance a rotary transformer in both coupling efficiency and transmission efficiency by a method wherein a core is enhanced in plane accuracy and restrained from deterioration in effective permeability. CONSTITUTION:A stator core SC out of component parts which constitute a rotary transformer is formed of a core (ferrite sintered core) which is formed by press-molding ferrite powder, and a rotor core RC is formed of a core (ferrite resin core) which is obtained by injection-molding ferrite resin obtained by kneading high molecular material binder and ferrite powder together. |
