Abstract
Provided are an inexpensive, high-quality, permeation-side flow path material that is suitable for use in spiral membrane elements and enables the improvement of productivity, a method for producing such a permeation-side flow path material, and a membrane element having such a permeation-side flow path material. Provided are (a) a permeation-side flow path material for use in a spiral membrane element, the permeation-side flow path material comprising a resin sheet comprising a plurality of ridge portions 31 formed parallel to one another; and a plurality of openings 32 formed between each pair of the ridge portions 31, (b) a method for producing such a permeation-side flow path material, and (c) a membrane element having such a permeation-side flow path material.
