Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a coil part which inhibits variations of Q-characteristics by inhibiting quantitative variations in an adhesive adhering to a core and prevents the core from being broken.
SOLUTION: In the method of manufacturing the coil part, an elastic plate 102 comprised of silicon rubber is placed on the upper surface of metal frame 101. Subsequently, a kapton tape is cut off to form a kapton sheet and the kapton sheet is placed on the elastic plate 102. Then, an adhesive is applied to the kapton sheet. Positions in which the adhesive is applied are approximate centers in the longitudinal and width directions of the kapton sheet, and only a minimum necessary amount of the adhesive is applied to secure the kapton sheet to a drum core with the adhesive. Then, the drum core around which a conductive wire is wound is pressed one by one to the kapton sheet on the elastic plate 102 via the adhesive to manufacture the coil part 1.

Abstract: PROBLEM TO BE SOLVED: To provide a coating stripping method of an insulated conductor that makes it possible to strip its coating unfailingly without deteriorating the properties of the conductor. SOLUTION: At the stripping portion 1C specified at the end of the insulated conductor, pulse laser is radiated on the surface of a core wire 1A. Its surface temperature is caused to rise sharply, so that polyamideimide constituting an insulation coating 1B of an interface 1a causes a chemical change of gasification without melting and a bubble 1b is generated on the interface 1a. The bubble 1b is expanded instantly to explode and scatter the coating 1B. Through these coating stripping processes, the insulation coating 1B at the stripping portion 1C is stripped.
