Zusammenfassung:	To provide a base fabric for air bags that avoids an increased environmental load and facilitates recycling.SOLUTION: In order to secure gas impermeability, a base fabric for air bags 1 has a substrate 3. A coating agent is applied to at least one side of the substrate, forming a coating layer 4 thereon. The coating agent is an aqueous coating. The substrate is composed of a woven fabric of polyamide fiber, polyester fiber, or polypropylene fiber. The coating layer can be washed off with water. Air permeability at a 20kPa differential pressure is set to be less than 3.0 L/cm2/min or air permeability by a Frazier method (JIS L 1096) is set to be less than 3.0 mL/cm2/sec.SELECTED DRAWING: Figure 1 【課題】環境への負荷の増大を抑制できて、かつ、リサイクル利用が容易なエアバッグ用基布を提供すること。【解決手段】ガス非透過性を確保するために、コート剤を塗布されて形成される塗膜４を基材３の少なくとも片面に有する構成のエアバッグ用基布１。コート剤が、水性塗料である。基材が、ポリアミド繊維、ポリエステル繊維、あるいは、ポリプロピレン繊維を織成してなる織布から、形成される。塗膜が、水洗除去可能な設定とされる。２０ｋＰａ差圧下における通気度を、３．０Ｌ／ｃｍ2／ｍｉｎ未満、若しくは、フラジール法（JIS L 1096）における通気度を、３．０ｍＬ／ｃｍ2／ｓｅｃ未満に、設定されている。【選択図】図１
