A resin-laminated board includes a front-side sheet and a backside sheet layered on each other with a hollow part interposed therebetween. The backside sheet is recessed toward the hollow part to provide a plurality of first recesses and a plurality of second recesses. The front-side sheet and the backside sheet are connected to each other with plural ribs by welding bottoms of the first recesses and the second recesses to the front-side sheet. The resin-laminated board has a thin-plate part having the first recesses with small depth and a thick-plate part having the second recesses with large depth, and the first recesses and the second recesses are arranged at substantially the same pitch.
