Abstract
An airbag is formed of two base fabrics. An adhesive agent is pasted with some width on one of the base fabrics and then another of the base fabrics is put on the one of the base fabrics. The two fabrics are adhered together to form the airbag. Pasting start/end portions of the adhesive agent is set at a gas introducing portion of the airbag. Pasting start/end points (terminal ends of the start/end portions) is located outside a path in the gas introducing portion through which a gas is introduced into an inside of the airbag. According to an airbag with the airbag, assembling workability of the airbag can be improved.
