To achieve compactification of a metallic collar, while comparatively highly keeping sealability by a resin material between an igniter and the metallic collar in an igniter assembly.SOLUTION: In the igniter assembly having an igniter, a metallic collar arranged around the igniter and a resin joining part joined by a resin material so as to integrate both in a noncontact state of the igniter and the metallic collar, the metallic collar comprises an annular surface formed in an annular shape so as to enclose the periphery of a part of the igniter in a joining state, and the annular surface comprises a joining surface part for contacting with the resin joining part by being covered with the resin joining part. An annular joining groove into which the resin material of the resin joining part enters, is formed in layers in the axial direction of the metallic collar in the joining surface part of the metallic collar.SELECTED DRAWING: Figure 3 【課題】点火器組立体における点火器と金属製カラーとの間の樹脂材料による密閉性を比較的高く保ちつつ、金属製カラーのコンパクト化を実現する。【解決手段】点火器と、点火器の周りに配置される金属製カラーと、点火器と金属製カラーとが接触しない状態で両者を一体化させるように樹脂材料で接合する樹脂接合部と、を備える、点火器組立体において、金属製カラーは、接合状態において点火器の一部の周囲を囲むように環状に形成された環状面を有し、該環状面は樹脂接合部に覆われて該樹脂接合部と接触する、接合面部を有する。そして、金属製カラーの接合面部に、樹脂接合部の樹脂材料が入り込む、環状の接合溝を金属製カラーの軸方向に重ねて形成する。【選択図】図３
