PROBLEM TO BE SOLVED: To provide a method for producing a base cloth for an air bag, having excellent storability and a required base cloth strength. SOLUTION: The method for producing the base cloth for the airbag comprises a step for weaving by using a high-strength fiber yarn B together with a warp yarn and/or a weft yarn when carrying out the weaving by using a fiber yarn A having 7.0-12 cN/dtex raw thread strength and the high-strength fiber yarn B having≥15 cN/dtex raw thread strength, regulated so that the shrinkage in boiling water of the fiber yarn A may be≥6% larger than that of the high-strength fiber yarn B, a step for carrying out shrinking finish by hot water, and a step for carrying out drying finish, so that the crimp rate of the fiber yarn in the obtained base fabric for the airbag may satisfy a specific relation.
