Abstract: There is provided a method for manufacturing a resin laminate in which a resin laminate having a foamed resin layer and a non-foamed resin layer can be efficiently manufactured, and a resin laminate having good surface properties can be obtained. A method for manufacturing a resin laminate 14A formed by laminating a foamed resin layer 6B and non-foamed resin layers 7A and 7A and having at least one foamed resin layer 6B, comprising steps of feeding a foamable resin composition 6 in an unfoamed state in a molten state and non-foaming resin compositions 7 and 7 for forming the non-foamed resin layers 7A and 7A into a mold 3 for sheet molding to form a resin laminate; and feeding the above resin laminate in which the foamable resin composition 6 is in an unfoamed state or a foamed state to a sizing die 4.
