(57) [Abstract] [Purpose] In a membrane separation module, a membrane having a low energy surface is securely and firmly sealed between a membrane and a case without surface treatment. A hollow fiber bundle 2 composed of a plurality of hollow fiber membranes 1 formed of an olefin-based polymer or a fluorine-containing polymer is housed in a case 3, and at least one end surface of the hollow fiber membranes 1 is opened. In this state, the hollow fiber bundle 2 and the case 3 are adhesively sealed with a sealant. By using the sealant containing the epoxy resin and the aromatic amine, a membrane separation module in which the hollow fiber bundle 2 and the case 3 are firmly adhered can be obtained. |
