To provide an airbag device configured so that spaces of sewing margins of panel parts to be arranged at a connection port of an airbag can be reduced.SOLUTION: An airbag 30 of an airbag device comprises a connection port part 33 through which gas G for inflation from an inflator 20 connected thereto is flown out to an inflation site. In the connection port part are arranged an outer panel part 70 and an inner panel part 51 to be arranged at an inner periphery side of the outer panel part. The inner panel part is formed by folding in two an inner sheet 55 forming the inner panel part and sewing overlapped peripheral edges 55b with each other. In the outer panel part, an outer sheet 74 forming the outer panel part is arranged to wrap the inner panel part and is sewn with the inner sheet and then arranged. The outer sheet is sewn with the inner sheet, in a state where sewing margins 67 of respective sewn parts 66 of the overlapped peripheral edges of the inner sheet folded in two are overlappingly pressed against one side 58 of the overlapped peripheral edges of the inner sheet across a sewn site.SELECTED DRAWING: Figure 4 【課題】エアバッグの接続口部に配設されるパネル部の縫代のスペースを低減できるエアバッグ装置を提供すること。【解決手段】エアバッグ装置のエアバッグ３０が、接続されたインフレーター２０からの膨張用ガスＧを膨張部位に流出させる接続口部３３を備える。接続口部には、外側パネル部７０と、外側パネル部の内周側に配置される内側パネル部５１と、が配設される。内側パネル部は、内側パネル部を形成する内側シート５５を、二つ折りし、重ねた周縁５５ｂ相互を縫合して形成される。外側パネル部は、外側パネル部を形成する外側シート７４を、内側パネル部を包むように配置させ、かつ、内側シートと縫合させて、配設される。外側シートは、二つ折りした内側シートの重ねた周縁相互の縫合部６６の縫代６７を、縫合部位を間にした内側シートの重ねた周縁の一方側５８に、重ねるように押し付けた状態として、内側シートと縫合される。【選択図】図４
