An air bag is made by forming a base cloth into the shape of a bag by stitching. The air bag is expanded by gas supplied from an inflator. Stitching of areas of the base cloth in the vicinity of the inflator is made non-extendable stitching, and stitching of areas of the base cloth distant from the inflator is made extendable stitching. As a result, even if the output of the inflator is high, gas leakage in the vicinity of the inflator can be prevented. Also, even if the output of the inflator is high, it is possible to suppress damage suffered by stitching thread in areas of stitching in the vicinity of the inflator.
