ABSTRACT:
In the metal piece 32 which diffuses into the fuse element so that an alloy layer is generated, there is formed an expanding slot 30, which is inserted and pressured in the fusing portion 25b of the fusible body 25 which forms the fuse element. Due to the foregoing, the metallic mass 32 of low fusing point is fixed to the fusible body 25 while it surrounds the circumferential surface of the fusing portion 25b.
