- 摘要：
PROBLEM TO BE SOLVED: To provide a separation membrane module of high water permeability and high performance, which hardly allows an organic substance, protein, platelet or the like to adhere to itself.
SOLUTION: This is a polysulfone-based separation membrane which includes a polysulfone-based polymer and a hydrophilic polymer and also includes in itself a component which is insoluble in N,N-dimethyl acetamide, wherein (a) the concentration of the polysulfone-based polymer in the insoluble component is at least 10 wt.% and at most 50 wt.%, (b) the water content of the insoluble component is at least 95 wt.%, and (c) a flexible layer, which is at least 7 nm in thickness, exists on the surface of the functional layer of the separation membrane of wet state.
