By the present invention, a method is obtained for efficiently and inexpensively providing a resin laminate having a foamed resin layer without the use of an adhesive. A method for manufacturing a resin laminate is provided with the steps of supplying a molten foamable resin composition (11) in a non-foamed state to a first manifold (4) of a multi-manifold mold (1), supplying a second resin composition (12) for forming a non-foamed resin layer to a second manifold (5), and, in the multi-manifold mold (1), merging and extruding the foamable resin composition (11) to a layering part (3) from the first manifold (4) and releasing pressure to cause foaming and forming a foamed resin layer (11A), and extruding a non-foamed resin layer (12A) extruded from the second manifold (5) and layering the non-foamed resin layer (12A) on the foamed resin layer (11A) prior to solidification of the foamed resin layer (11).
