ELECTRIC WIRE WITH TERMINAL AND MANUFACTURING METHOD FOR ELECTRIC WIRE WITH TERMINAL

To reduce the cost of an electric wire with a terminal and improve the strength of joining of an electric conductor of the electric wire and a terminal of the electric wire.SOLUTION: An electric wire with a terminal includes an electric wire having an electric conductor made of a plurality of metallic strands, and a terminal to which the electric conductor is joined, the electric conductor is joined to the surface of the terminal, the back surface of the terminal has a first type joining mark, the electric conductor has a second type joining mark on the side opposite to the side in contact with the terminal, the surface roughness of the first type joining mark is rougher than the surface roughness of the second type joining mark. The first type joining mark is a joining mark corresponding to the horn of an ultrasonic bonding machine, and the second type joining mark is a joining mark corresponding to an anvil of an ultrasonic bonding machine.SELECTED DRAWING: Figure 1 【課題】端子付き電線のコストを抑えて接合の強度を向上させる。【解決手段】端子付き電線は、複数の金属素線よりなる導体を有する電線と、前記導体が接合される端子とを有し、前記導体が前記端子の表面に接合されており、前記端子の裏面に第１種の接合痕を有し、前記導体において前記端子と接している側と反対側に第２種の接合痕を有し、前記第１種の接合痕の表面粗さが前記第２種の接合痕の表面粗さより粗い。第１種の接合痕は、超音波接合機のホーンに対応した接合痕であり、第２種の接合痕は、超音波接合機のアンビルに対応した接合痕である。【選択図】図１
