くさせていた。However, if the clearance of the press die is adjusted or the die is worn, as shown in FIG. 8, punch burrs 8 are likely to be generated at the front end during punching by the press, and the burrs are slid. The opposing substrate is scratched during operation, causing abnormal wear, and the contact resistance is increased, thereby significantly deteriorating the contact reliability.

ものである。According to the technical means of the present invention for solving the above-mentioned problems, one end face is rounded or both ends in the thickness direction are inclined.
It is formed into a corner having a (tapered) portion and is used for punching a sliding contact having the end face as a contact portion.

いても適用されるものである。According to the strip material for punching a sliding contact of the present invention having the above-mentioned structure, the end face is previously formed in a round shape or a plate thickness.
Since the corners having inclined (tapered) portions at both ends are formed and the contact portions are formed, no burrs are generated at the tip. In addition, since the end face is punched as a contact portion, it is possible to use a strip having a minimum width as compared with the conventional one, which is advantageous in terms of efficiency, yield, and cost. Furthermore, since the end face is formed by the band material, deburring is not required as in the related art, and the productivity is high without deformation. It should be noted that, as shown in FIG.
In addition to mechanical processing such as compression molding and cutting molding, chemical and mechanical polishing are appropriately performed. Of course, a composite (cladding) band joined at the end faces is also effective.
Furthermore, the present invention is also applied to the tip of an insertion / extraction connector as a sliding contact.
