An airbag fabric is excellent in slippage amount and strength in a sewn portion. The airbag fabric is made of a synthetic fiber, the fabric having a constant (load of 98 N/30 mm) elongation of 1 to 5% and having a residual strain rate of 0.1 to 1.5%, the residual strain rate being obtained when the fabric is allowed to stand still for 10 minutes from the removal of the 98 N/30 mm load after the retention of the fabric for 10 minutes while the 98 N/30 mm load is applied to the fabric. The strength in the sewn portion is preferably 1200 N or more in each of the warp and the weft.
