Abstract: [Object]. An object is to suitably control the deployment shape of an airbag, thereby improving the occupant restraining performance. Another object is to reduce damage to an occupant located close to a steering wheel or an instrument panel.[Solving Means]. An airbag device according to the present invention includes: a gas generator that generates expansion gas; an airbag that expands and deploys due to the expansion gas to restrain an occupant; and a diffuser disposed inside the airbag to control a flow of the expansion gas. Given that a direction toward the occupant is a first direction, the diffuser includes a receiving surface disposed between the gas generator and the airbag in the first direction to receive the expansion gas discharged from the gas generator; and a plurality of band-like connecting members having one end connected to an edge of the receiving surface and the other end directly or indirectly connected to the gas generator.
