An upper end of the gap is in communication with the upper fluid channel and a lower end of the gap is in communication with the lower fluid channel. An upper end opening of each of the membrane elements is open to outside of the module main body and a lower end opening each of the membrane elements is closed. A vertical partition plate is provided in either the upper fluid channel or the lower fluid channel to form an inlet chamber and an outlet chamber. ## Claims ### Claim 1 A separation membrane module comprising: an upper horizontal partition plate positioned in an upper portion within a module main body so as to form an upper fluid channel;
