ABSTRACT:
A plurality of holes 2, each of which permits insertion of a small-diameter of an article to be manufactured, are formed in a flexible metal retaining plate 1 having a thickness of about 100 micrometers. A pair of notches 3, 3 are formed in the internal periphery of each hole 2 so as to be opposite to each other, and a cantilever 4 is defined between a pair of the notches 3, 3. The small-diameter portion of the article to be manufactured is inserted into each hole 2, and the cantilevers 4 and the hole 2 are integrally fixed together by welding. A plurality of the articles to be manufactured retained by the retaining plate 1 are fed as a unit to a surface abrasion step, a film-forming step, and others. As a result, a plurality of sensor elements can be simultaneously manufactured.
