PROBLEM TO BE SOLVED: To provide a method for producing a resin laminated board for outside plates, which board has uniform thickness and excellent surface properties after thermoformed.SOLUTION: The method for producing the resin laminated board for outside plates comprises the steps of: preparing a resin laminated body 1 which has a heat decomposition type foaming agent-containing foamable resin layer 4 and first and second reinforced resin layers 2, 3 which are disposed so that the foamable resin layer 4 is held between them; and molding the prepared resin laminated body 1 into a desired shape by using a thermoforming metal mold and utilizing the heat when a foamable resin, which comprises the foamable resin layer 4, is heat-foamed. The step of molding the prepared resin laminated body 1 is carried out while heat-foaming the foamable resin or after the foamable resin is heat-foamed.SELECTED DRAWING: Figure 1
