Abstract

A separation membrane complex includes a support, a separation membrane, and a coating membrane. The support includes a porous portion and a dense portion that are arranged continuously. The separation membrane is provided on the porous portion of the support. The separation membrane has an end portion that is in contact with the dense portion. The coating membrane is composed by a layered inorganic compound. The coating membrane coats a boundary portion between the dense portion and the separation membrane.
