The present invention provides a hollow fiber membrane module having fixing layers to which one or more hollow fiber membrane bundles each including a plurality of hollow fiber membranes are fixed at respective ends thereof using a casting resin, a hollow portion of each of the hollow fiber membranes being open at one or both of the ends, wherein the hollow fiber membrane bundle is divided into a plurality of small bundles at at least one of the fixing layers on the open side of the hollow portion, and an outer circumference of each of the small bundles is covered with an elastic body near a filtration portion interface of the fixing layer.

La présente invention concerne un module de membrane de fibre creuse dans lequel un ou plusieurs faisceaux de membrane de fibre creuse, chacun étant composé d'une pluralité de membranes de fibre creuse, comprennent chacun des couches fixées, fixées par une résine de coulée aux deux extrémités et une partie creuse de la membrane de fibre creuse est ouverte à une ou aux deux extrémités. Dans au moins une couche fixée sur le côté sur lequel la partie creuse est ouverte, le faisceau de membrane de fibre creuse est divisé en une pluralité de petits faisceaux, et la périphérie externe de chacun des petits faisceaux est recouverte avec un élément élastique à proximité d'une interface avec une partie de filtration de la couche fixée.
