PROBLEM TO BE SOLVED: To constitute a miniaturized and inexpensive occupant protection device for a vehicle by reducing the number of parts of a noise protection circuit while ensuring noise protection performance. SOLUTION: The air bag device is provided with a squib; an ignition circuit; and a noise protection circuit. Then, the noise protection circuit comprises two Zener diodes opposedly connected with a cathode and is connected to the squib in parallel. Thereby, the ignition circuit is protected from noise and the air bag device can be made to miniaturization to low cost by reducing the number of parts of the noise protection circuit.
