PROBLEM TO BE SOLVED: To satisfactorily achieve removal of lead in Sn system of a fuse element that is integrated in an electrical components as a tantalum capacitor, while satisfactorily ensuring stable mounting of fuse-integrated electrical components with lead-free soldering or prevention of carbonizing and smoking of electrical components, when fusing action works. SOLUTION: This is a fuse element composed of a binary alloy with liquids temperature of 300 deg.C to 550 deg.C, that is Sn blended with either Cu, Pt, Pd, Ti, Ni, Mn, Mg, Ge or Al.
