PROBLEM TO BE SOLVED: To provide a non-coated woven fabric for air bags, which can keep an excellent low gas permeability required for woven fabrics for the air bags, and the low gas permeability also after an environmental aging test. SOLUTION: There is provided the non-coated woven fabric for air bags, includes synthetic filament yarns having a total fineness of 200 to 700 dtex and a single filament fineness of 1 to 2 dtex, wherein the initial gas permeability of the woven fabric is not more than 0.50 L/cm<SP>2</SP>/min, when measured at a test differential pressure of 19.6 kPa, and the gas permeability after the woven fabric is subjected to a thermal aging treatment for 400 hrs in an environment of 120°C is not more than 150% based on the initial gas permeability.
