Abstract:
This separation membrane is provided with: a separation membrane main body which has at least a base and a separating function layer; and a flow channel member which has a composition different from that of the separation membrane main body and is affixed to the base-side surface of the separation membrane main body. The flow channel member is arranged such that the flow channel member is discontinuous in a first direction but is continuous in a second direction from one end to the other end of the separation membrane main body.
