Abstract
A hollow fiber membrane module 10 includes: a plurality of hollow fiber membranes 200; a case 100 that accommodates the plurality of hollow fiber membranes 200 and has a case main body 110 made of a resin and having openings at both ends thereof; and a pair of sealing and fixing portions 310 and 320 that seal a gap between the hollow fiber membranes in a state where a hollow inside of each of the hollow fiber membranes 200 is kept open and fix the plurality of hollow fiber membranes 200 to the case 100 on both end sides of the case 100. In the case main body 110, a reinforcement portion 115 that connects a pair of facing wall surfaces of inner wall surfaces for accommodating the plurality of hollow fiber membranes 200 is integrally provided on the pair of wall surfaces.
