摘要： The present invention relates to a method for producing a hollow fiber membrane sheet-like object including: a connecting process of forming a ring-shaped section by winding a hollow fiber membrane capable of being continuously supplied, around two or more rolls so as to surround the two or more rolls and connecting a leading end portion of the wound hollow fiber membrane and an adjacent hollow fiber membrane, or of putting a ring-shaped section created in advance, on two or more rolls, and connecting a leading end portion of a hollow fiber membrane capable of being continuously supplied, to the ring-shaped section; a winding process of winding the hollow fiber membrane around the rolls by moving the leading end portion of the hollow fiber membrane by rotating at least one roll of the two or more rolls; a fixing process of forming a fixed section by fixing the hollow fiber membrane wound around the two or more rolls, into the form of a sheet in a width direction; and a cutting process of performing cutting-out along the fixed section, thereby obtaining a sheet-like object to which end portions of the hollow fiber membranes are connected in the width direction. According to the present invention, a hollow fiber membrane sheet-like object can be produced with a simple configuration and a change in sheet length can be easily performed.
