A cutoff device includes a conductor wire, a pyrotechnic circuit breaker, a plurality of drive circuits connected to the pyrotechnic circuit breaker in parallel and configured to activate the pyrotechnic circuit breaker, and a control circuit. The control circuit sets an output current value and a period for which the output current is output to each of the drive circuits, and causes the drive circuits to supply the power for activating the pyrotechnic circuit breaker when the pyrotechnic circuit breaker needs to be activated.
