PROBLEM TO BE SOLVED: To provide a base cloth for a non-coat airbag for a high pressure extension, excellent in housing property while maintaining the strength and low air permeability necessary as the air bag, and a fiber for the airbag giving the base cloth for the airbag. SOLUTION: This base cloth for the airbag by using a synthetic fiber multi- filament having 1.5-8.0 flatness ratio of the cross section of its monofilament, <=10 dtex monofilament fineness, 200-1,000 dtex total fineness in both warp yarn/weft yarn or one of them satisfies the following (1) to (3) simultaneously. (1) A cover factor is 1,700-2,200. (2) An air permeability (PL) under a low pressure is <=0.1 cc/cm<2> /sec. (3) An air permeability (PH) under a high pressure is <=20 cc/cm<2> /sec.
