To provide a circuit abnormality diagnostic device capable of diagnosing abnormality of a circuit simply and easily, a current generation device equipped with the circuit abnormality diagnostic device, an expanded body injection device for a flying body equipped with the current generation device, an air bag device for a flying body equipped with the current generation device, and a cutting device for a flying body equipped with the current generation device.SOLUTION: A circuit abnormality diagnostic device 110 includes an arithmetic unit 1, a power source 2 for inspection, a rectifier 3, resistors 4 and 5 for overcurrent protection, a voltage amplification unit 6, a voltage reading unit 7, and a light emission unit 8, and executes abnormality diagnosis on a circuit for each preset time (including the time of initial loading) or for each predetermined time. The circuit abnormality diagnostic device 110 executes diagnosis (determination) as: a normal state when a voltage value is in the range of a first voltage value V1 to a second voltage value V2 preset as a range of the voltage value indicating that the circuit is normal; a short-circuit state in which the circuit is short-circuited when the voltage value is lower than the voltage value V1; and a disconnection state in which the circuit is disconnected when the voltage value is higher than the voltage value V2.SELECTED DRAWING: Figure 2
