Separation membrane module

A separation membrane module comprising:

• a hollow module container;
• and an element unit which is housed in the module container,
• wherein the element unit comprises a plurality of separation membrane elements which are connected to each other, the separation membrane elements including a separation membrane for separating components of a substance flowing into an inside of the module container, and a membrane bundle fixing material for fixing both ends of the separation membrane, and a flow channel for discharging the components separated by the separation membrane to outside of the element unit is formed in the element unit,
• wherein passage members through which the components separated by the separation membranes can pass toward the flow channel for discharging the components are disposed at connections between the plurality of separation membrane elements such that both end surfaces of each of the passage members are respectively in contact with the membrane bundle fixing materials of the separation membrane elements adjacent thereto,
• wherein the passage member is formed of a single member, and
• wherein the passage member is formed of a porous member having fluid permeability.
