があった。(Problems to be Solved by the Invention) In the above manufacturing method, when the linear base material 1 is clad with a Cu alloy and the strip contact material 4 is clad with a soft material such as Ag, When the flat upper surface of the strip-shaped contact material 4 is formed into the arc-shaped upper surface 5 by rolling and drawing, the joint surface with the linear base material 1 is left and right as shown in FIG. 6 because the strip-shaped contact material 4 is soft. In some cases, the sagging 6 occurred from both ends, and the linear base material 1 was covered with the left and right side surfaces. Since this droop 6 is not adhered to the linear base material 1, when the electric contact wire rod 3 is cut into an appropriate size and used as an electric contact, the droop 6 rises or falls off due to vibrations or the like to generate electricity. There was a problem that it interfered with the contact of the contacts.

When the contact surface of the strip-shaped contact material is formed into an arc shape by rolling and wire drawing after clad with the strip-shaped contact material, the notch step serves as an escape area for the contact material. Therefore, even when a soft material such as Ag is used for the strip-shaped contact material, the sagging of the contact material and the sagging of the linear base material on both left and right side surfaces do not occur. Thus, when the electrical contact wire rod manufactured by the manufacturing method of the present invention is cut into an appropriate size and used as an electrical contact, the contact failure due to the covering of the base material of the conventional one does not occur, which is high. It is reliable.
