Provided is a method of manufacturing an electric wire with terminal formed by connecting a first core exposed portion of an electric wire to a metal terminal having a box portion that is formed by processing a single conductive board into a box shape and has an opening in which a counterpart terminal is inserted, and a spring inside the box portion. After laser-welding opposed portions where parts of the single conductive board forming the box portion are opposed to each other, applying ultrasonic vibration to a second core exposed portion of the electric wire is executed.

Method of manufacturing electric wire with terminal and electric wire with terminal

In a terminal-attached electric wire applied to a wire harness, a metal terminal includes: an electric wire connection portion to which the electric wire is connected; a box-shaped portion that is formed into a box shape by a bottom body coupled to the electric wire connection portion and a pair of wall bodies formed by protruding individually from both ends of the bottom body in a width direction, and enables a counterpart terminal to be inserted into a terminal insertion space portion in an inside thereof along an axial direction intersecting the width direction; and a spring contact portion that is located inside the terminal insertion space portion, is elastically deformably supported in the box-shaped portion in a cantilever manner, and forms a contact with the counterpart terminal, and wherein the box-shaped portion has a displacement regulating portion that regulates a relative displacement between the pair of the wall bodies.
