PURPOSE:To prevent generation of a crack resulted from a resin clear layer between an outside circumferential insulating layer and an outest circumferential insulating layer on a terminal plate by a method wherein the terminal plate is exposed on the surface of the coil. CONSTITUTION:A base material and a conductor are alternately wound around a spool 1 to form the coil 2. Then terminals 4 are fixed to the terminal plate 3, and a mold releasing treated part 12 is formed on the upper faces of the terminal plate 3 and the terminals 4. After leads 5 are connected to the terminals 4, a filler 6 is filled up on the circumference of the leads 5, the outside circumferential insulating layer 7 and the outest circumferential insulating layer 8 are wound around, the winding finishing part is sealed to form a seal part 9, and the elemental coil 10 is constituted. After thermosetting resin containing photosetting resin is impregnated making the elemental coil 10 in condition putting the seal part 9 on the lower side, ultraviolet rays are irradiated to the circumferential face of the coil to apply the leakage preventing treatment by formation of a film, resin is heated to be hardened, and after resin is cooled gradually, the spool 1 is pulled out. Then the outside circumferential insulating layer 7 and the outermost circumferential insulating layer 8 on the terminal plate 3 are removed to expose the outside surface of the terminal plate 3. |
