PURPOSE:To prevent burrs from being generated at the time of forming by a method wherein a portion where a terminal is installed is made in the form of a projection coated with thermoplastic resin and incorporated in a metallic mold. CONSTITUTION:A spool 10 is made of elastic thermoplastic resin and its projection 10d has been provided with a terminal 11 in it. A linear conductor 12 is wound on the cylinder of the spool 10 and the front end of the winding is electrically connected to a portion to be soldered of the terminal 11 to form a coil proper 15. A metallic mold is located in between a cavity 16a corresponding to the principal portion of the coil body, a gap 16f for exposing the terminal 11 and between the periphery of the cavity 16a and the gap 16f. The mold is composed of a upper mold 16c a fitting piece 16b thereof is smaller than the projection 11d in dimension and a lower mold 16d. The coil body 15 is arranged in the metallic mold and the projection 10d is pressed and fixed with the fixing piece 16b. The coil body is incorporated in the mold by injecting the thermoplastic resin 17 in the cavity 16a. |
