An air bag (8) comprises two resin sheets (1, 2) of which peripheries arenbonded to each other. At least one of the resin sheets (1, 2) has a rough surface facingnthe inside of the air bag (8). Therefore, the resin sheets (1, 2) are prevented from adheringnto each other even when they are overlaid on each other for a long time, therebynpreventing the air bag (8) from not being inflated when gases are supplied to the insidenof the air bag (8). |
