Disclosed are an airbag fabric having excellent air-tightness and improved durability, and a method for manufacturing the same with high productivity. The method of the present invention comprises the steps of: preparing a fiber substrate; and forming a coating layer on at least one surface of the fiber substrate. The step of forming the coating layer includes the steps of: preparing a coating solution by adding a crosslinking agent and a thickener to water-dispersed polyurethane, wherein the crosslinking agent has a blocked active group and the thickener is a hydrophilic thickener; applying the coating solution on at least one surface of the fiber substrate; drying the fiber substrate applied with the coating solution; and thermally treating the dried fiber substrate.
