Abstract
Disclosed are an edge member for membrane elements that can effectively improve adhesion with exterior finishing materials, and a membrane element that is equipped with the same. A plurality of types of undulations (134, 135) of different shapes are formed on the circumference of an extension (132) that extends from the main body (131) of an anti-telescoping member (edge member for membrane element) (13) toward a membrane roll body (11), and an exterior finishing material is attached to extend across the circumference of the extension (132) and the circumference of the membrane roll body. The adhesion between the anti-telescoping member (13) and the exterior finishing material can thus be effectively improved, since the exterior finishing material can be attached to the circumference of the extension (132) with the plurality of types of undulations (134, 135) in contact with the exterior finishing material.
