Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a fuse which has stable blowout characteristics and can be easily manufactured.

SOLUTION: A fuse 600 comprises: a fuse element 100 provided between a pair of terminal parts 110 and having a plurality of blowout parts 120; and a casing 200 for housing the blowout parts 120. The fuse element 100 is bent in a longitudinal direction P of the fuse element 100, and has a first flat surface 140 and a second flat surface 150 linearly extending in the longitudinal direction P. The first flat surface 140 and the second flat surface 150 are provided with the plurality of blowout parts 120. The first flat surface 140 and the second flat surface 150 are continuous with each other at a bent part 131.
