<p>PROBLEM TO BE SOLVED: To provide a gasket spacer used for an electrodialyzer capable of effectively suppressing the degradation of sealing property and the deterioration of surface smoothness or the like although having such a structure that a net and a gasket frame are integrated by thermal bonding in the gasket spacer arranged between ion exchange membranes adjacent to each other of an electrodialyzer.SOLUTION: In the gasket spacer 10 arranged between ion exchange membranes adjacent to each other of an electrodialyzer, a part made of a thermoplastic net 1 and a thermoplastic gasket frame 3, in which the surrounding of the net 1 is fastened to the gasket frame 3 by thermal fusion and filament bodies of the net 1 are thermally fused is located on an inner part of the gasket frame 3, are flattened and have an elliptical traverse section 1a'.</p> |
