Abstract: A sliding contact producing method is provided wherein noble metal balls are easily positioned on a metal plate; the weld strength between the noble metal ball and the metal plate can be obtained sufficiently; and a noble metal mounting jig can be prevented from damage when the metal plate is beam-welded with the noble metal ball. While being received in the recess portions of a jig, the noble metal balls are respectively contacted with bowllike recesses formed in the base surface of the metal plate.

The present invention can improve welding operation efficiency and the reliability of welded portions. Since the metal plate being wider than that of the resilient strip receives beam, the metal contact mounting jig can be prevented from damage due to beam welding.
