Abstract
(EN)
The present invention provides a fuse that has stabilized fusing characteristics and that is easy to manufacture. A fuse 600 provided between a pair of terminal parts 110, the fuse 600 comprising a fuse element 100 having a plurality of fusing parts 120, and a casing 200 that accommodates the fusing parts 120, wherein the fuse 600 is characterized in that: the fuse element 100 has a bent shape along the length direction P of the fuse element 100, and comprises a first flat surface 140 and a second flat surface 150 that extend in linearly along the length direction P; the plurality of fusing parts 120 are provided to the first flat surface 140 and the second flat surface 150; and the first flat surface 140 and the second flat surface 150 are continuous with each other in a bent section 131.
