PROBLEM TO BE SOLVED: To provide a multilayer structured plate which is not warped over a long period of time after produced and can be used as a mount for display panels, and to provide a production method of the multilayer structured plate.SOLUTION: The multilayer structured plate 10 includes a polystyrene resin expanded plate 1. A first adhesive layer 22, a first paper layer 23 and a first resin layer 24 are arranged in this order on one surface of the polystyrene resin expanded plate 1. A second adhesive layer 32, a second paper layer 33 and a second resin layer 34 are arranged in this order on the other surface of the polystyrene resin expanded plate 1. The moisture content of the first paper layer 23 and that of the second paper layer 33 are equal to or lower than 10 mass%, respectively and the absolute value of [the moisture content (mass%) of the first paper layer 23]-[that (mass%) of the second paper layer 33] is 1.5 or lower. |
