PROBLEM TO BE SOLVED: To provide a fusible link that makes it easier to achieve downsizing by reducing a distance between a pair of terminal boards without deteriorating the degree of freedom for the design of pre-arcing time-current characteristic in a fusible part connecting the pair of terminal boards even when the distance between the pair of terminal boards is decreased.SOLUTION: A fuse element 20 formed of a metal plate is housed in a fuse housing made of insulating resin. The fuse element 20 includes a fusible part 21 to be fused when a current larger than a rated current flows through; and a pair of terminal boards 22 and 23 conductively connected to each other with the fusible part 21 interposed therebetween. The fusible part 21 has at an intermediate part thereof a fuse facilitating part 25 formed into a bellows structure obtained by bending a belt-shaped metal plate 251 into a waveform or zigzag shape. |
