ABSTRACT:
A fuse element which includes a substantially beltlike fusible body for electrically connecting a pair of connecting terminal portions to each other, the connecting terminal portions connected to an electric circuit, a low-melting-point metal piece clamped and fixed onto a melting metal adding portion arranged on the fusible body in order to adjust a fusion characteristic of the fusible body, and a pair of clamping pieces formed to extend outward from both side edges of the melting metal adding portion of the fusible body for clamping and fixing the low-melting-point metal piece set on the melting metal adding portion from both sides of the low-melting-point metal piece, in which the pair of clamping pieces have projections for holding the low-melting-point metal piece in press contact with each other by projecting into a space defined by a width of the melting metal adding portion when the clamping pieces are upwardly bent from both sides of the melting metal adding portion.
