A technique of improving pressure resistance performance of an igniter assembly is provided. The igniter assembly includes an igniter body including an ignition portion filled with an igniting charge and an electro-conductive portion extending from the ignition portion, an igniter collar including a tubular peripheral wall portion that surrounds at least the electro-conductive portion of the igniter body, and a resin molded article that is interposed between the igniter body and the igniter collar and integrates the igniter body and the igniter collar. The igniter collar includes a first support portion that is provided in an inner peripheral portion of the peripheral wall portion and is formed in a convex shape toward an inner side of the peripheral wall portion in a radial direction and thus buried in the resin molded article and a second support portion that is provided at a position in the inner peripheral portion proximal to the first support portion from the ignition portion in a direction along a center axis of the peripheral wall portion and is formed in a convex shape toward the inner side of the peripheral wall portion in the radial direction and thus buried in the resin molded article or formed in a concave shape toward an outer side of the peripheral wall portion in the radial direction and thus filled with the resin molded article.
