Abstract
A fuse comprising: a fusible portion constituted by a connection portion which is formed of the same metal base material as a pair of terminals so as to connect the pain of terminals to each other, and a low-melting metal having a melting point lower than that of the connection portion and stacked by welding on at least a portion of the connection portion; and at least one protrusion formed on the fusible portion by making the connection portion and the low-melting metal project in a direction parallel to the plane of an interface between the connection portion and the low-melting metal. Further disclosed is a method of manufacturing the fuse. The fuse can be manufactured with a simple manufacturing process in comparison with a conventional method, and in the fuse, only the fusing-off time in a layer short-circuit range can be shortened by use of diffusion between the low-melting metal and base material.
