1. An airbag device, comprising:
a gas generator including a first gas generating agent that generates a combustion gas by ignition and an ignition unit configured to ignite the first gas generating agent; and
an airbag configured to inflate upon receiving supply of the combustion gas from the gas generator, the airbag including,
an inlet connected to the gas generator, the inlet being configured to cause the combustion gas supplied from the gas generator to flow into an internal space of the airbag,
a bag-shaped portion that is a bag-shaped body configured to separate, from an outside, the internal space into which the combustion gas flows from the inlet, the bag-shaped portion being configured to be in a folded state before receiving the supply of the combustion gas and to be in an inflated state by receiving the supply of the combustion gas, and
a second gas generating agent that is disposed at a predetermined position on an inner surface of the bag-shaped portion and generates gas by using thermal energy of the combustion gas without accompanying a combustion reaction.
