An air bag (8) comprises two resin sheets (1, 2) of which peripheries are bonded to each other. At least one of the resin sheets (1, 2) has a rough surface facing the inside of the air bag (8). Therefore, the resin sheets (1, 2) are prevented from adhering to each other even when they are overlaid on each other for a long time, thereby preventing the air bag (8) from not being inflated when gases are supplied to the inside of the air bag (8). <IMAGE> |
