PROBLEM TO BE SOLVED: To provide an inner fabric used in a down-proof structure concerning the down-proof structure which is excellent in a down blowout-preventing effect, excellent in shape recoverability, when the down is blow-charged or used, has a soft touch, retains the down blowout-preventing effect, even when the fabric is used for a long time or highly frequently used, and is excellent in durability, to provide an inner bag for the down, and to provide the down-proof structure using the inner bag. SOLUTION: The inner fabric for the down is formed laminating a high density nonwoven fabric and an inner cotton nonwoven fabric on each other, the high density nonwoven fabric is a nonwoven fabric containing ultra fine fibers of <0.5 dtex as constituting fibers and having an air permeability of 16 to 100 (cm3/cm2*s), and the inner cotton nonwoven fabric includes fibers having an average fineness of 0.5 to 5 dtex, and has a thickness of 5 to 20 mm, and a surface density of 50 to 200 g/m2.
