A method of manufacturing a resin-laminated board by preparing a pair of first and second split molds each of which is provided with a cavity; positioning two sheet materials made of a thermoplastic resin between the first and second split molds with the cavities of the first and second split molds opposed to each other; forming a plurality of recesses by recessing a first sheet material toward a second sheet material with use of a plurality of protrusions provided to the first split mold; and welding bottoms of the recesses to the second sheet material by clamping the pair of first and second split molds to obtain a resin-laminated board with a hollow structure. A mold includes a plurality of piece members, disposed at the cavity of the first split mold; and includes the protrusions and male screws provided to base ends of the protrusions.
