A humidifying membrane module that is reduced in weight and size and can be manufactured at low cost by forming a case in a single-layer structure is provided. The humidifying membrane module has a hollow fiber membrane bundle constructed from a plurality of hollow fiber membranes, the case for accommodating the hollow fiber membrane bundle, a first flow passage extending through hollow inner portions of the hollow fiber membranes, and a second flow passage extending through the outer wall surface sides of the hollow fiber membranes. The hollow fiber membrane bundle and the case are simultaneously integrated with each other at both ends of the hollow fiber membrane bundle by using potting members for sealing gaps between the hollow fiber membrane bundle and the case. An inlet and an outlet for forming the first flow passage are formed respectively at the both ends of the case. An entrance and an exit for forming the second flow passage are formed respectively in side surfaces near the both ends of the case. |
