The method for producing a hollow fiber membrane layer laminate includes a plurality of hollow fiber membranes, and is constituted by a laminate in which a plurality of hollow fiber membrane layers constituted by the plurality of hollow fiber membranes are laminated. A hollow fiber membrane layered laminate having the shape of a cylindrical body, wherein the hollow fiber membrane is reciprocated in the central axis direction of the cylindrical body while being wound around the central axis of the cylindrical body. A step of winding the hollow fiber membrane layer, in which the hollow fiber membranes adjacent to each other in the central axis direction of the cylindrical body are spaced apart by a predetermined distance, in the radial direction of the cylindrical body, When the speed increase rate z is a value obtained by dividing the pitch between the hollow fiber membranes adjacent to each other by the reciprocating distance of the traverse, the winding step goes to the hollow fiber membrane layer on the outer side in the radial direction of the cylindrical body. Accordingly, the speed increase rate z is reduced.中空糸膜層積層体の製造方法は、複数本の中空糸膜を有し、該複数本の中空糸膜で構成された中空糸膜層が複数層積層された積層体で構成され、全体形状として円筒体の形状をなす中空糸膜層積層体を製造する方法であって、前記中空糸膜を、前記円筒体の中心軸回りに巻回しつつ、前記円筒体の中心軸方向に往復動させて、前記円筒体の中心軸方向に隣り合う前記中空糸膜が所定距離離間した前記中空糸膜層を前記円筒体の径方向に積層する巻回工程を有し、前記円筒体の中心軸方向に隣り合う前記中空糸膜間のピッチをトラバースの往復距離で除算した値を増速率ｚとしたとき、前記巻回工程では、前記円筒体の径方向の外側の前記中空糸膜層に行くに連れ、前記増速率ｚを小さくする。
