Abstract: An airbag (1) constituted by using a laminated cloth comprising a woven fabric (2a) of synthetic fiber multifilaments, a film (3) of a polyolefin group resin laminated on a side of the woven fabric (2a) and a nonwoven fabric (4) laminated on the film (3). The laminated cloth has a weight per unit area of 280 g/m.sup.2 or less and an air permeability of 2 cc/cm.sup.2 or less. The air bag having the constitution in accordance with the present invention has synthetically superior characteristics as an air bag for a driver's seat, a passenger's seat, or others, in a vehicle.
