An airbag device is provided with a double-woven coated airbag in which average values of the number of warps and wefts per square inch in double-weaving are 49 to 50 in one embodiment or 51 or more in another embodiment. With the airbag, peak inner pressure values before and after completion of expansion are set corresponding to the coating weight of the coating agent on the basis of a straight-line formula for a relationship between peak inner pressure values and the coating agent at the time of inflowing of the expansion gas.
