To provide a hollow fiber membrane module for moisture exchange which can sufficiently humidify dried oxidant gas supplied into hollow fiber membranes, and can suppress the unevenness of filled hollow fiber membranes to allow the humidified off gas to flow uniformly.
The hollow fiber membrane module for moisture exchange includes a cylindrical case, a plurality of the hollow fiber membranes axially extended and filled in a space inside the case, sealing portions for fixing the hollow fiber membranes and sealing the space at the both ends of the case, an introduction port formed on one side of the case, a discharge port formed on the side opposite to the side formed with the introduction port, a first fluid path extending from one end side to the other end side of each of the hollow fiber membranes through the hollow inside thereof, a second fluid path extending from the introduction port to the discharge port through the inside of the space and the outside of the hollow fiber membranes, a plurality of porous members axially extending in the space and having planes traversing the second fluid path, and support members axially extending in the space, coming into contact with and supporting the porous members and having a rigidity higher than that of the porous members.
