PROBLEM TO BE SOLVED: To provide a gas separation membrane module for organic vapor separation with a hollow fiber element which proves to be damageproof when separating an organic vapor. SOLUTION: At least, one end part of a hollow fiber bundle composed of a large number of hollow fiber membranes with selective permeability, is anchored and united together by a tube plate made of a curable resin, as the makeup of a hollow fiber element constituting a separation membrane module for organic vapor separation. In addition, perforations opened only in the permeation-side space, are arranged in the solid part of the tube plate. COPYRIGHT: (C)2009,JPO&INPIT
