PROBLEM TO BE SOLVED: To enhance the low dusting characteristics of a separation membrane module used for ozone dissolution etc. SOLUTION: The all-fluororesin membrane module is constituted so that a separation membrane element integrally formed by bundling the ends of a plurality of fluororesin separation membranes, and sealing the ends with a fluororesin and contained in a housing made of the fluororesin which is provided with a cylindrical body and caps provided in the axial direction for closing the openings on both ends of the cylindrical body. The cap installed on one end of the cylindrical body is provided with a fluid inflow path for flowing into the housing and the separation membrane element is provided with a fluid inflow path, while the cap on the other end is provided with a fluid outflow path for flowing from the housing and the separation membrane element is provided with a fluid outflow path. The pipe connection sides of the fluid inflow path and the fluid outflow path of the caps on both ends are integrally projected with joints and external threads are formed on the outer peripheral surfaces of the joints. The tips of the pipes are externally fit to the joints protruding from the cap outer surfaces so that they are connected by screwing. COPYRIGHT: (C)2009,JPO&INPIT
