To provide a technique concerning a filter molding for a gas generator excellent in filtration effect and cooling effect of combustion gas and, moreover, excellent in shape retaining property and manufacturing easiness than heretofore.SOLUTION: A filter molding for a gas generator includes a circumferential wall part which extends a groove part formed on one place in a circumferential direction of metal wire material having a circular or an elliptical transverse cross-section along a drawing direction of the metal wire material and has a hollow cylinder shape formed of a circumferential surface on a part other than the groove part, a gas flow face which is formed by either one side face of an inner circumferential face and an outer circumferential face of the circumferential wall part and allows gas to inflow to the circumferential wall part and a gas outflow part which is formed by either the other face of the inner circumferential face or the outer circumferential face, and causes gas to outflow from the circumferential wall part. Therein, the groove part is oriented so as to open toward the gas inflow face on the circumferential wall part.SELECTED DRAWING: Figure 8 【課題】燃焼ガスの濾過効果及び冷却効果に優れ、しかも、従来よりも保形性及び製造容易性に優れたガス発生器用のフィルタ成形体に関する技術を提供する。【解決手段】ガス発生器用のフィルタ成形体であって、円形又は楕円形の横断面を有する金属線材の円周方向における一箇所に形成された溝部が金属線材の延伸方向に沿って延在すると共に溝部を除く部位に円周表面が形成されたフィルタ線材の巻回体によって形成された、中空筒形状を有する周壁部と、周壁部の内周面及び外周面の何れか一方の面によって形成され、周壁部にガスを流入させるガス流入面と、周壁部の前記内周面及び外周面の何れか他方の面によって形成され、周壁部からガスを流出させるガス流出面と、を備え、溝部は、周壁部におけるガス流入面に向かって開口するように配向されている。【選択図】図８
