Abstract
A shutdown device includes: a pyro-fuse that includes a bus bar inserted into a power supply path and a piston disposed above the bus bar, the piston moving toward the bus bar to divide the bus bar; and a melting fuse connected in parallel to the pyro-fuse, in which the melting fuse includes a fuse case, a fuse element provided in the fuse case and is fused when an overcurrent flows, and an arc-extinguishing material provided in the fuse case and being in a granular phase, and the fuse element extends along a direction intersecting a direction in which the piston moves.
