To ensure that an inner bag, an air bag, and so on are not damaged by a high-temperature/high-pressure gas from an inflator, the present invention provides a head protecting air bag device including: an inflator 1; an air bag 11 constituted by a plurality of chambers 11c that are deployed when the gas ejected from the inflator 1 is supplied thereto from a connecting portion 11a via a duct 11b; and an inner bag 12 provided in the connecting portion 11a of the air bag 11. A protective band 15 is provided on an inner surface of a part of the inner bag 12 that opposes a gas ejection hole 1a in the inflator 1 when the inflator 1 is attached to the air bag 11. Hence, the high-temperature/high-pressure gas can be received by the protective band, and therefore the inner bag, the air bag, and so on are not damaged by the high-temperature/high-pressure gas ejected from the inflator.
