A membrane element includes a central pipe having, in its outer periphery, holes; a membrane wound body in which a membrane member is wound on the central pipe; end members arranged, respectively, at both ends of the membrane wound body; and an exterior member fitted to at least an outer periphery of the membrane wound body. In this element, the exterior member includes a fiber reinforced resin having a reinforcing fiber wound on the outer periphery of the membrane wound body; the end members each includes flexible portions extended from a main body toward the membrane wound body; and the reinforcing fiber is wound also onto an outer periphery of the flexible portions in a state that the flexible portions are deformed toward an outer peripheral surface of the membrane wound body.
