PROBLEM TO BE SOLVED: To obtain a three dimensional fibrous structure, improved with its ventilation property and water absorption, not exhibiting a sticky feeling on sweating and having unevenness by knitting with setting the ratios of the thickness and amplitude of yarns within a specific range. SOLUTION: This three dimensional fibrous structure having a surface area ratio of its unevenness part as 1 part protruded part to 1-5 recessed part, and consisting of base textures of surface and rear, and a joining yarn for joining them, is obtained by using 2 kinds of yarns having different thickness in (1:2)-(1:6) total decitex ratio and having 20-660 total decitex as the yarns constituting the above base textures and knitting by using (1:2)-(1:6) amplitude of the yarns and making the amplitude of the thick yarn as larger than that of the thin yarn.
