The purpose of the present invention is to provide an airbag-use non-coated woven fabric that achieves light in weight, compact in size, and low air permeability, and an airbag-use woven fabric having low air permeability, being flexible, and exhibiting good package ability without impairing mechanical strength of the woven fabric, and an airbag that uses the airbag-use woven fabric. The airbag-use woven fabric including a base fabric, wherein a yarn widening ratio of unwoven weaving yarn of fibers that constitute the base fabric is not less than 2.4 and not more than 3.5, or including single yarn fibers having a substantially triangular cross sectional shape and a modification degree of 1.3 to 2.2; having a tear strength of not less than 120 N; and having an air permeability under a pressure difference of 20 kPa of not more than 0.65 L/cm2/min.
