Abstract
A method for manufacturing a crimp terminal having a crimp portion that allows crimp connection to a conductor part of a coated wire includes forming a tubular body by bringing together side edges of a plate material made of metal composed of a copper alloy having a copper content ratio of greater than or equal to 70%, irradiating a periphery of the sides edges, which are brought together, with laser light from a laser irradiation unit to weld the side edges which are brought together, and setting a power density of the laser light and a sweep rate of the laser light in such a manner that a weld bead formed at the side edge portion after the welding has a width of 80 μm to 390 μm.
