ABSTRACT:
A method for producing a fuse element having a fusible portion and any other portion which are made of different kinds of metal. The method comprises the steps of boring through-hole in a substrate made of first metal, forming an element plate by fusion-bonding a second metal to the through-hole and integrally stamping a pair of substrate portion made of the first metal and a low-melting-point portion made of the second metal. The second metal is made of a metal whose melting point is lower than that of the first metal. Further, the pair of substrate portion is connected together by the low-melting-point portion so that the fuse element is formed.
