Abstract
Provided is a hollow fiber membrane module that allows reducing pressure loss of a dry gas and a moist gas. A hollow fiber membrane module has: a hollow fiber membrane bundle; a case in which the hollow fiber membrane bundle is accommodated; a pair of sealing and fixing parts that fixes the hollow fiber membrane bundle to the case; intra-membrane channels; and extra-membrane channels. Moisture in the moist gas is supplied into the dry gas by virtue of the membrane separation effect of the hollow fiber membranes. A first channel is provided, which runs through the case from one end side to the other end side and through which part of the dry gas flows without passing through the intra-membrane channels.
