Abstract
A hollow fiber membrane module that increases a ratio of a membrane area contributing to membrane separation effect. On an inner wall surface of a case 100, at least one flow-straightening projection 130 and at least one flow-disturbing projection 140 are provided. The flow-straightening projection 130 projects toward an outer circumferential surface of a hollow fiber membrane bundle 300 to secure a gap between the inner wall surface of the case 100 and the hollow fiber membrane bundle 300 and extends from one end side toward the other end side of the case 100 and straightens a flow of fluid. The flow-disturbing projection 140 extends along a circumferential direction of the case 100 and disturbs the flow of the fluid.
