せ、突出表面で接点を構成したものである。Here, the manufacturing process will be described. First, as shown in FIG. 2, the contact materials 11, 11 are provided on the surface of the wide base material 10 and in the shaded area in FIG. Is the contact material 11, 11 provided as a composite material by the clad method or the inlay method,
It is provided flat on the surface of the base material 10 by a plating method. next,
The base material 10 is cut as shown by the chain double-dashed line in FIG. 2, and the contact material portion is projected from the back surface and projected to the front surface side, and the contact surface is constituted by the projected surface.

用が少なくて済み安価となる。EFFECTS OF THE INVENTION As is apparent from the above description, according to the present invention, a contact material such as gold or silver is flatly provided on the surface of a conductive plate-shaped metal base material by inlay, clad, plating, or the like. Since the contact material part is projected from the back surface and the contact is composed of the protruding surface,
It is possible to omit a welding process which is complicated and has high precision in positioning parts and the like and which is also costly, and the transfer of electrodes and the roughness of the electrode contact surface are eliminated, so that the contact reliability is improved. In addition, the height of the contact material can be secured by the protruding base material portion, and the use of the contact material (noble metal) can be reduced accordingly and the cost can be reduced.
さらに、接点の裏面は凹状となっているため、放熱面
積が増加し、放熱効果が良好であるという利点を有す
る。Further, since the back surface of the contact is concave, there is an advantage that the heat dissipation area is increased and the heat dissipation effect is good.
