1. A separation membrane element comprising a pair of separation membranes containing two separation membranes arranged so that the filtrate-side surfaces thereof are disposed in mutually opposed relation, a peripheral sealing member disposed between and sealed to peripheral edges of the pair of the separation membranes, and a multiplicity of individual resin members extending between the separation membranes and bonded to both of the mutually opposed filtrate-side surfaces, wherein the resin members 1) are positioned in and maintain a predetermined gap between the separation membranes such that the gap functions as a flow channel between the separation membranes, and 2) cause discontinuous shadows when projected onto the separation membrane.
