摘要： 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.

摘要： A barrel portion which allows the pressure-bonding connection of an aluminum core wire exposed on a distal end of an insulated wire covered with an insulating cover is formed into a cylindrical shape by bending barrel portion corresponding portions of a terminal base material in a terminal developed state about a terminal axis. In abutting end portions where the barrel portion corresponding portions abut each other, a welded part which welds the end portions is formed along a long length direction of the insulated wire. The welded part is formed on an upper surface concave portion and a projecting portion where an amount of plastic deformation of a conductor pressure-bonding section generated along with the pressure-bonding of the conductor pressure-bonding section becomes larger compared to other portions in a circumferential direction of the conductor pressure-bonding section.
