description | PROBLEM TO BE SOLVED: To provide a fusible link, capable of easily installing a low-melting point metal for erosion diffusing a metal conductor of a fusing part without caulking work. SOLUTION: This is the fusible link which is equipped with the fusing part at one part of a metal plate to form a conductive passage, and in which the fusing part is arranged vertically. An input side part of a width W1, a solder coating part which is continued to the lower end of the input side part and which has a wider width W2 than the width W1; a fusing part which continues to the lower end of the solder coating part, and which has a narrower width W3 than the width W1; and an output side part of the width W1 which is continued to the lower end of the fusing part are installed vertically in a stage state, by matching the upper and lower center axial lines; a surface of the solder coating part is coated by solder of a lower melting point than that of the metal plate, the solder is fused earlier than the metal plate when energized by more than an allowable energizing amount, and made to flow down by own weight; and a fusing speed of the fusing part on the lower side is accelerated by the fusing solder.
