Abstract
After bringing a conductor of an electric wire into press contact to connect with a wire caulking portion of a connection terminal, the conductor and the wire caulking portion are welded to connect by irradiating laser beam to a bottom wall of the wire caulking portion. Laser irradiation is carried out intermittently by three times and the laser irradiation at the second time and thereafter which is carried out later is carried out such that during a time period in which a laser welded portion immediately previously is brought into a predetermined state of elevating temperature, portions or welded regions overlap welded regions in laser irradiation irradiated previously.
