Abstract
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.
