In an air bag device, a diffuser 5 is provided with a partition wall 51 partitioning a space on a case opening side of the diffuser 5 into a passenger side and a side further from the passenger; a gas guiding passage 7 for guiding gas produced by an inflator 4 to a case opening 21 is formed on the side of this partition wall 51 further from the passenger, a folded air bag 3 is packed on the passenger side of the partition wall 51, and a case-side end portion 32a of an air bag upper part 32 to constitute the upper part of the deployed air bag is disposed so as to cover the exit of the gas guiding passage 7. As a result, the end portion 32a of the air bag upper part 32 is expanded first and the air bag subsequently deploys progressively and smoothly from this air bag upper part 32 side in a controlled manner.
