An inflator includes a compressed gas chamber defined by closing an exit hole with a rupture plate, a housing which holds a gas generator which can rupture the rupture plate and which has discharge ports from which a compressed gas can be discharged to the outside, and a guide for guiding a combustion gas from the gas generator to the rupture plate so as to rupture the rupture plate. The guide includes a substantially cylindrical spouting tube portion which extends toward the exit port at a distal end thereof, a mounting seat which is disposed at a proximal portion of the spouting tube portion and a connecting portion disposed between the mounting seat and the spouting tube portion. The guide is installed so as to be held to a holding tube portion with the spouting tube portion extending towards the exit port while defining a space H between an inner circumferential surface of a connecting tube portion of the housing and the spouting tube portion so extending and the mounting seat kept in abutment with a riser surface of the housing.
