Description of the Related Art A hollow fiber membrane module has a structure in which a plurality of hollow fiber membranes are bundled, and at least one end of the hollow fiber membrane is held in an open state and is adhesively fixed to a housing with a potting agent. The hollow fiber membrane module causes the non-fixed hollow fiber membranes to vibrate, stretch, shrink, etc. around the boundary between the fixed and non-fixed portions of the hollow fiber membranes during running or handling, thus fixing the hollow fiber membranes. There is a problem that the boundary portion becomes fatigued and a leak from the boundary portion easily occurs.

ある。However, in the method of providing the protective layer made of a flexible material after potting the hollow fiber membrane, when the filling rate of the hollow fiber membrane is high, it becomes very difficult to inject a uniform protective layer material, and a special protective layer is used. I need a jig. In addition, in the method of providing the elastic layer at the end of the hollow fiber membrane before potting the hollow fiber membrane, the end face of the potting portion is cut to expose the end face of the elastic resin layer to the end face of the module. When the layer material cannot be used and the adhesiveness of the elastic layer forming material to the hollow fiber membrane or the potting agent is low, there is a problem that leakage occurs when the module is used.

Examples of the hollow fiber membrane suitable for supplying air to a liquid include a three-layer structure hollow fiber membrane in which a homogeneous membrane having a function of separating gas by dissolution and diffusion is sandwiched between porous membranes and combined.
The three-layer structure hollow fiber membrane has a composite structure in which a thin homogeneous membrane having a gas-permeable gas separation function is sandwiched from both sides by a porous membrane with high mechanical strength that does not hinder gas permeation. It has advantages that it is not easily scratched and its handling property is good. In addition, if the porous membrane is made of a water-repellent polymer, even if degassing is performed for a long time, water vapor etc. will condense into the porous membrane and become water droplets, blocking the pores of the porous membrane and permeating the gas of the membrane. It has advantages such as stable degassing for a long time without deteriorating the property.
