<p>An igniter assembly which can prevent a gap from being generated due to shrinkage of resin and can easily manufacture a collar, and an inflator and an airbag device using the igniter assembly are disclosed. The igniter assembly (10) includes an igniter (20), a substantially cylindrical collar (30) for holding the igniter (20), and resin (40) for joining the igniter (20) to the collar (30). The collar (30) has a cylindrical main body (31), a collar portion (32) provided inward at the inner circumferential surface of the main body (31), and a cylindrical surrounding wall portion (33) which extends from one end of the main body (31) in the axial direction of the main body (31). A groove (50) is formed in a radial surface (32b) of the collar portion (32) at the side of the surrounding wall portion (33).</p> |
