A case for a hollow fiber membrane module (1) provided with a through-hole (2) serving as a fluid flow channel in a wall surface, wherein the case for a hollow fiber membrane module has rounded ribs (4, 4', 4'', …) provided to an acute angle edge portion of the through-hole on the inner side of the case, and is furthermore preferably provided with a mesh in the through-hole on the inner side of the case. This case for a hollow fiber membrane module is capable of reducing damage when an accommodated hollow fiber membrane module is used in comparison with a conventional case for a hollow fiber membrane provided with a through-hole serving as a fluid flow channel in a wall surface. |
