Hollow fiber membrane module

Provided is a hollow fiber membrane module capable of improving durability. In a hollow fiber membrane module (1), a support body (3) has holding parts (41, 42), pillar parts (51, 52), and reinforcing members (6, 7). The holding parts (41, 42) respectively hold the end parts (21A, 21B) of the hollow fiber membrane (21), and the pillar parts (51, 52) are respectively connected to the holding parts (41, 42) and support the holding parts (41, 42). The reinforcing members (6, 7) are members for reinforcing the connection between the holding sections (41, 42) and the pillar sections (51, 52). Each of the holding parts (41, 42) is provided with a connection part (30) that is formed so as to be able to connect to the respective pillar parts (51, 52). The reinforcing members (6, 7) are formed so as to be attachable to the connection section (30). The reinforcing members (6, 7) have protruding portions (63, 73) that protrude toward the connecting portions (30) or the pillar portions (51, 52). 提供能够提高耐久性的中空纤维膜组件。在中空纤维膜组
