PURPOSE: A membrane module is provided to improve the efficiency and the durability of the membrane module by dividing a space to which a negative pressure is applied. CONSTITUTION: A membrane module includes a frame(10) and a filtering membrane(21). Slit-shaped water paths are concavely formed on the surface of the frame. Convex parts are formed between the water paths. One convex part is expanded to an edge side to divide a confluent path. The confluent path is formed at one side of the water paths and is perpendicularly arranged to the water paths to be in connection with the water paths. The frame forms a water suction hole(3) and a water collecting path. The suction hole applies a negative pressure to supply water introduced into the water paths to the outside. The water collecting path collects treating water at one place and transfers the collected water to the suction hole. The filtering membrane is attached on the surface of the frame.
