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.

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.
