PROBLEM TO BE SOLVED: To provide an airbag device capable of being mounted at various kinds of portions by reducing the size, weight and cost of the airbag device with little discharge gas from an inflator, to protect an occupant by reducing speed by optimum pressure. SOLUTION: An airbag 12 comprises a first airbag 25 formed by arranging a plurality of substantially the same triangle-shaped and ring-shaped frame bodies 21 and 22 side by side on right and left sides by communicating center space parts 23 and 24 with each other and connecting the frame bodies 21 and 22 without a gap, and a second airbag 28 formed by closing the center space parts 23 and 24 of the first airbag 25 by closing members 26 and 27. When the first airbag 25 is deployed and inflated to a triangle and ring shape by gas generated by the inflator 11 during a collision, etc., atmospheric air is sucked into the center space parts 23 and 24 of the first airbag 25 from check valves 26a and 27a and intake/exhaust holes 26b and 27b, and the second airbag 28 is deployed and inflated, while holding atmospheric air inside by making the first airbag 25 as an outer frame.
