PROBLEM TO BE SOLVED: To provide a multilayer resin sheet from which a foaming wall paper having excellent scratch resistance while having sufficient interlaminar adhesiveness can be produced even under a high-temperature and high-humidity environment; to provide a layered sheet; to provide methods for producing such a multilayer resin sheet and such a layered sheet; and to provide a method for producing a foaming wall paper.SOLUTION: The multilayer resin sheet includes: a first layer including a foaming agent-containing resin composition including a first resin and a foaming agent; and a second layer including a foaming agent-free resin composition including a second resin and no foaming agent. In the multilayer resin sheet, the first resin includes an ethylene homopolymer or a copolymer of ethylene and another olefin, containing 50 mol% or more of an ethylene unit, and the second resin includes a polyethylene having a density of 0.920 g/cmor more.SELECTED DRAWING: None
