PURPOSE:To provide an electromagnetic converter with little leakage flux, by a method wherein an electromagnetic converting member is covered by a film of high permeability and a film of high conductivity. CONSTITUTION:An electromagnetic converting member 501 is composed of a laminated core of U-shaped or C-shaped type and a winding member surrounding the core, and coated with an insulation resin 502. The resin 502 is covered by a resin 503 mixing material of high permeability. The resin 503 is further covered by a resin 504 mixing metal of high conductivity. Thus the electromagnetic converter covered by the film composed of double layer of the resin 503 and the resin 504 can prevented the internally generated electromagnetic wave from leaking outwards and also prevents the external interference electromagnetic wave effectively. |
