(57) [Summary] [PROBLEMS] To provide an elastomer molded article having water swelling anisotropy, which is extremely high in water swellability in a specific direction. [Composition] A composite sheet obtained by coating a woven fabric or a non-woven fabric with a high water-swelling elastomer, a composite sheet obtained by laminating a high water-swelling elastomer single sheet on a woven fabric or a non-woven fabric, or a plurality of the composite sheets. It is an elastomer molded product having a water swelling anisotropy, which is a laminated body in which the above are laminated and integrated. |
