A fusible link includes a power supply portion provided on a connection terminal that connects to a battery terminal, a circuit terminal that connects to a circuit, a power-supply side upstanding portion standing in an out-of-plane direction of a terminal mounting surface from an edge substantially parallel to an extending direction of the battery terminal out of an outer circumferential edge near the power supply portion of the connection terminal, a circuit-side upstanding portion standing in the same direction as the power-supply side upstanding portion from an edge substantially parallel to the extending direction out of an outer circumferential edge of the circuit terminal, and a bridge portion extending between the power-supply side upstanding portion and the circuit-side upstanding portion. The power-supply side upstanding portion, the circuit-side upstanding portion, and the bridge portion function as a fuse element that fuses when a current greater than a threshold value flows.
