Provided is a resin-laminated board that can improve the stiffness further while securing the weight and thickness reduction. A resin-laminated board includes a front-side sheet 120A and a backside sheet 120B layered on each other with a hollow part interposed therebetween. The backside sheet 120B is recessed toward the hollow part to provide a plurality of first recesses 200S and a plurality of second recesses 200L. The front-side sheet 120A and the backside sheet 120B are connected to each other with plural ribs by welding bottoms of the first recesses 200S and the second recesses 200L to the front-side sheet 120A. The resin-laminated board has a thin-plate part 100a having the first recesses 200S with small depth and a thick-plate part 100b having the second recesses 200L with large depth, and the first recesses 200S and the second recesses 200L are arranged at substantially the same pitch.
