The invention belongs to the technical field of wood processing, and discloses a novel mildew-proof laminated board of a cabinet and a manufacturing method of the novel mildew-proof laminated board. Toona ciliata var. pubescens micro-veneer layers which are conducted mildew-proof treatment are glued on the upper surface and the lower surface of a base material layer of the laminated board of the cabinet of the novel laminated board of the mildew-proof cabinet; the base material layer of the laminated board of the cabinet comprises one of a plywood, a medium-density fiberboard and a solid-wood finger joint laminated board; the manufacturing method comprises the steps that processing treatment is conducted on toona ciliata var. pubescens micro-veneer, sanding of the plywood, the medium-density fiberboard and the solid-wood finger joint laminated board are conducted, a thermo-plasticity film adhesive is prepared, assembly, hot-pressing, trimming deflashing and edge banding are conducted, and the novel laminated board of the mildew-proof cabinet is acquired. According to the novel mildew-proof laminated board of the cabinet and the manufacturing method of the novel mildew-proof laminated board, by adopting materials of a new tree species to replace the micro-veneer produced by rear tree species, the production cost is reduced, the width of the micro-veneer can be cut out freely according to the specification of a product; and the manufacturing deficiency is effectively decreased, the production efficiency is improved, and the surface of a laminated product is attractive.
