An actuator includes: a gas generator which generates an operation gas when actuated; an accommodation-side portion which accommodates and holds the gas generator; and a push-side portion which is pushed by the operation gas generated from the gas generator to advance relatively so as to move away from the accommodation-side portion, wherein: a seal material which realizes watertightness between the push-side portion and the accommodation-side portion before actuation is provided in an external surface side portion between the push-side portion and the accommodation-side portion by being poured and set through molding; and the seal material doubles as an adhesive which enables the push-side portion to move relatively when actuated and which provides a joining force with which the push-side portion can be restricted from moving relatively before actuation so as to join the push-side portion and the accommodation-side portion together.
