The airbag includes a first bag to be inflated and deployed in a vehicle width direction along a front edge part of a hood of a vehicle, and a second bag to be inflated and deployed on an upper surface of the hood. The second bag is continuous with a vehicle rear side portion of the first bag. An internal space of the first bag and an internal space of the second bag communicate with each other through a first vent mechanism. The first vent mechanism is opened when an internal pressure of the first bag reaches a predetermined pressure.
