Abstract

The present invention has an object of providing an electric wire connection structure for providing sufficiently high electric characteristics by welding and fixing a terminal and core wires, for providing the terminal with a strength sufficiently high to withstand the pressure at the time of welding, and for improving the adhesiveness of the core wires to the terminal by preventing the core wires from escaping at the time of welding. The electric wire connection structure is for connecting core wires (10) exposed at a tip end of a coated wire (12), including the core wires (10) covered with a insulating cover (11), to a conductive terminal (20). The terminal (20) includes a caulking portion (23) in which the core wires (10) are to be held by caulking, and a welding portion (22) to which the core wires (10) are to be fixed by welding. The caulking portion (23) and the welding portion (22) are arranged in a base portion of the terminal (20) in a longitudinal direction thereof. The welding portion (22) of the terminal (20) includes a positioning portion (24) on which the core wires (10) are to be placed, and holding walls (25), rising upward from an inner bottom surface (24a) of the positioning portion (24), for holding the core wires (10) from both sides thereof at the time of welding. The core wires (10) located in the welding portion) (22) are fixed thereto by welding.
