Abstract

A membrane element includes a filtration membrane and a flowpath member joined thereto. The flowpath member is made of yarn arranged into a three-dimensional structure, and includes inner spaces through which a permeated liquid permeated through the filtration membrane flows, and an outer bonding surface joined to the filtration membrane. At least part of the yarn forming the outer bonding surface is a low-melting point yarn having a softening point lower than that of a material forming the filtration membrane, or the yarn forming the outer bonding surface is formed by twisting a plurality of constituent yarns, and at least one of the constituent yarns is a low-melting point yarn having a softening point lower than that of the material forming the filtration membrane.
