SEPARATION MEMBRANE, SEPARATION MEMBRANE ELEMENT, AND METHOD FOR PRODUCING SEPARATION MEMBRANE

摘要

The present invention provides a separation membrane having a plurality of coneavoconvex parts which have a height difference of from 100 µm to 2000 pm and are formed on at least one surface of the separation membrane, in which an averagevalue dl of a minimum thickness and an average value d2 of a ma thicknessthe coneavoconvex parts satisfy the follow lational expression [1]: 0.8 dl/d21.0.
