PROBLEM TO BE SOLVED: To provide a ceramic hollow fiber membrane module improved in durability to breakage, or the like, by controlling thermal deformation while being used in a high temperature atmosphere by improving the structure of a bundle attachment tube for housing a bundle of a number of porous ceramic hollow fiber membranes. SOLUTION: Opening parts 2a (or 2b) for supplying/discharging gas are formed symmetrically at symmetrical equal arrangement positions on both sides of the central axis of the bundle attachment tube 2 to make thermal expansion uniform, thereby solving the problem that, when the opening parts are formed at unsymmetrical positions with only one position arranged on one side of a tube body, the tube 2 is distorted/deformed by thermal stress generated by receiving thermal influence unbalancingly to cause the breakage of the module.
