PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer laminated element having high gas permeability resistance and excellent durability. SOLUTION: Thermoplastic elastomer A, B, and vulcanized rubber C are laminated as a layer in order of an A layer/a B layer/a C layer. In the laminated element, the elastic modulus MA, MB, and MC of the elastomer A, B, and the vulcanized rubber C at 20°C and 2% distortion have a relation of MA/MB<0.8 and MC<MB.
