Abstract
A metallic ring molded by punching a copper plate having hooks , etc., and a carbon member are brazed to each other by a brazing material having a higher melting point than the temperature for connecting a coil to conductive members , that is, a brazing material containing, for example, nickel and chromium. Next, resin is filled up inside the metallic ring and carbon member to form a resin substrate . Next, slits are formed at the metallic ring and the carbon member in the radial direction, so that generally fan-shaped segments insulated from each other and conductive members are formed. Next, a coil is connected to hooks of the conductive members by soldering, welding, etc.
