To provide a method for simultaneously weaving a double woven base fabric for two or more air bags, free from a reed mark and little having fuzzes with an air jet loom in good production efficiency in a state little stopping the loom due to warps.

This method for weaving the double woven base fabric for air bags from polyhexamethylene adipamide yarns with an air jet loom is characterized by weaving the yarns at a yarn occupation index of 100 to 250 in a reed, at a loom rotation speed of 300 to 800 rpm, at a sub-nozzle distance of 3 to 10 cm, and in a width of ≥1.5 m. The yarn occupation index=0.106×n×√(D)/(P-T), wherein n is the number of yarns pulled in each dent; D is the fineness (dtex) of the polyhexamethylene adipamide yarn; P is a dent pitch (cm); T is a dent thickness (cm).
