An igniter assembly includes an igniter, a substantially cylindrical collar for holding the igniter, and resin for joining the igniter to the collar. The collar has a cylindrical main body, a collar portion provided inward at the inner circumferential surface of the main body, and a cylindrical surrounding wall portion which extends from one end of the main body in the axial direction of the main body. A groove is formed in a radial surface of the collar portion at the side of the surrounding wall portion. The resin is filled between the igniter and the inner circumferential surface and the radial surface of the internal hole of the collar portion and the inside of the surrounding wall portion so as to fill in the groove. The collar is easily manufactured, and the igniter assembly prevents a gap from being generated due to shrinkage of resin.
