Kind Code:
A
Abstract:
To reduce the possibility of forming a void.SOLUTION: Disclosed is a method of manufacturing a stator for a rotary electric machine which includes: a step of bringing a tip end part (40) of one coil piece (52) for forming a stator coil (24) of a rotary electric machine (1) into contact with a tip end part (40) of the other coil piece (52); and a welding step of irradiating a welding target location related to the abutted tip part with a laser beam (110).
