The present invention pertains to a fiber structure body that includes coil-shaped crimped fibers (a) and non-coil-shaped crimped fibers (b), wherein the fiber structure body has an entangled portion (A) constituted from the coil-shaped crimped fibers (a), and an entangled portion (B) constituted from the non-coil-shaped crimped fibers (b), the distance between at least one pair of entangled portions (B) in the flow direction of the fiber structure body being less than the apparent average fiber length of the coil-shaped crimped fibers (a).本發明關於一種纖維構造體，其係包含線圈狀捲縮纖維(a)及非線圈狀捲縮纖維(b)之纖維構造體，該纖維構造體具有由線圈狀捲縮纖維(a)所構成之纏合部分(A)與由非線圈狀捲縮纖維(b)所構成之纏合部分(B)，纖維構造體之流動方向中的至少1個纏合部分(B)彼此間之距離係未達前述線圈狀捲縮纖維(a)之表觀平均纖維長度。
