PROBLEM TO BE SOLVED: To provide a polyamide fiber structure having excellent see-through preventing properties, and excellent yellowing resistance, fastness against transition of dyeing and washing fastness even in a fabric dyed to a light color such as whitish color, skin color, yellow, pink or cream-color, and a method for manufacturing the same. SOLUTION: The yellowing-proof polyamide fiber structure is a knitted fabric of an elastic yarn and a core-sheath type conjugate yarn whose core part contains a white pigment. The knitted fabric is treated with an aqueous medium containing an acid anhydride, dyed and treated for finishing. The resultant fiber structure has a yellowing factor with vanillinΔYI of <=5 and L*- value of >=40.
