    • An airbag and an airbag device, which are capable of readily improving expansion characteristics of the airbag and reducing manufacturing cost, are provided. An airbag 11 for occupant at passenger's seat includes a first bag 21 and a second bag 22 which is provided inside of the first bag 21. An outside top face portion 36 of the first bag 21 and an inside top face portion 46 of the second bag 22 are brought into a sheet-like intimate contact with each other, and are detachably jointed at the jointing portion 51. The jointing portion 51 is comprised of a breakable seam line 52. Gas is supplied into the second bag 22 to thereby expand the first bag 22, and is supplied into the first bag 21 via a gas distributing portion 48 to thereby expand the first bag 21. In a case where an occupant exists at a predetermined position, the jointing portion 51 breaks away, and the first bag 21 then expands to its maximum. In an OOP state in which the occupant exists in the proximity of the airbag device 1, a head part of the occupant holds the outside top face portion 36 and disallows breakage of the jointing portion 51, so that expansion of the first bag 21 to the occupant side can be restrained and the occupant can be protected with an appropriate force.
