A seat-mounted airbag device is provided with: an airbag main body having a front-rear chamber and a front-end chamber; the front and rear chambers are deployed from a side portion of a headrest of a vehicle seat provided on a window side through a gap between a head of an occupant of the vehicle seat seated on the window side and a head of an occupant of the vehicle seat seated on a center side during a head-on collision, and are disposed in the gap, and the front end chamber is deployed inward from a front end portion of the front and rear chambers. The airbag main body is accommodated in the side portion in a state of having an outer roll portion, and the guide member protrudes from the side portion prior to deployment of the airbag main body and is located between the airbag main body and a head of an occupant seated in a vehicle seat at a center side. An airbag main body can be smoothly deployed even if a gap between the head of an occupant seated on a vehicle seat on a window side and the head of an occupant seated on a vehicle seat on a center side is narrow.
