摘要：
To provide a composite semipermeable membrane capable of maintaining high removal performance even after its supporting membrane has come into contact with an aqueous solution high in salt concentration. A composite semipermeable membrane including: a supporting membrane which includes a substrate and a porous supporting layer; and a separation functional layer provided on the porous supporting layer, in which a strength to peel the porous supporting layer away from the substrate is 1.1 N/25mm or higher.
