To provide a method for manufacturing a decorative product wherein a sliced veneer sheet can be excellently bonded without any trouble onto a plastic-made or metal-made base body surface.

After applying adhesives 30 to a base body 10 comprising plastic or metal (the first process), and the base body is covered by the sliced veneer sheet 20 (the second process). Thereafter, an inside of a decompression room 51 is reduced in pressure under a state wherein a work 1 is arranged inside the decompression room 51 of a vacuum press machine 50, the sliced veneer sheet is bonded to the surface 11 of the base body 10 and thereafter, the sliced veneer sheet 20 is pushed onto the base body 10 by feeding heated air into a pressurizing room 52, and the sliced veneer sheet 20 is bonded to the base body (the third process).
