Degassing module and method for degassing liquid

A degassing module comprising:

• a pipe including an in-pipe flow path having a liquid supply port and a liquid discharge port, the pipe having a plurality of holes that allow the in-pipe flow path to be open;
• a hollow fiber membrane group formed by winding hollow fiber membrane fabric around an outer circumferential side of the pipe so as to cover the plurality of holes, the hollow fiber membrane fabric having a plurality of hollow fiber membranes serving as wefts, and warps;
• a housing connected to an outer circumferential surface of the pipe and configured to store the hollow fiber membrane group;
• a partition unit configured to partition a region in the housing into an internal region including an inner circumferential side space of each of the plurality of hollow fiber membranes, and an external region including an inter-membrane space between the plurality of hollow fiber membranes;
• an air intake port of the housing, the air intake port communicating with the internal region;
• and
• a baffle configured to partition the in-pipe flow path and the inter-membrane space in an extending direction of the pipe,
• wherein a ratio of a diameter of each of the warps to a diameter of each of the plurality of hollow fiber membranes is 0.6 or higher.
