Abstract
A method for manufacturing a crimp terminal having a crimp portion adapted to allow crimp connection with a coated wire having a conductor and an insulating coating, the crimp portion being adapted to crimp connect along the coated wire from a portion of the conductor coated with the insulating coating to a portion of the conductor exposed from the insulating coating at a tip of the coated wire includes providing a barrel member formed by arranging edges of a copper alloy plate material side-by-side, the barrel member having a diameter reducing on an end portion side in a longitudinal direction from a coating crimp portion, forming the crimp portion by welding the edges by laser irradiation from a laser irradiation unit onto a position where the edges are arranged side-by-side, while moving a laser light irradiation position in a longitudinal direction of the barrel member, and irradiating laser light with an output power density and a sweep rate for causing fine molten metal particles having a diameter of 60 μm or less to ejected from the weld portion during laser welding to adhere to an inner surface of the barrel member.
