Gas supplied from gas discharge ports is guided without providing a metal guide tube on the inflator of an airbag device, and the airbag is protected from the gas. An inner tube (50) is connected to a gas inlet (13) formed in an airbag (10), and an inflator (40) around which a fabric member (60) is wound is inserted into and attached to a gas passage (54) formed in the inner tube (50). The fabric member (60) is wound around the inflator (40) several times into a tubular shape such that it covers a plurality of gas discharge ports (42) provided in the inflator (40) and such that one end thereof opens to the inside of the airbag (10), and the fabric member (60) is inserted into the inner tube (50). When the inflator (40) is activated, gas from the gas discharge ports (42) is guided to the inside of the inner tube (50) by the fabric member (60) and is guided and supplied to air chambers (31) and (32) through the gas passage (54), thereby inflating and deploying the airbag (10).
