A paperboard three-dimensionally molded pallet having sufficient rigidity in its load carrying surface and load bearing strength in its leg portions. The pallet is so designed that when it is finally treated as a waste, it can be recycled as new paperboard three-dimensionally molded pallets or a material for the other paper products requiring rigidity. The pallet comprises a paper-made plate-like top plate member (1) and paper-made cylinder-with-base legs (2). A plurality of through holes (15) is provided in the top plate member (1), and the cylinder-with-base-type leg (2) is inserted into the through hole (15) and then joined to the top plate member (1) with a water soluble adhesive agent. The top plate member (1) and the cylinder-with-base-type leg (2) are produced by placing a water-absorbed plane laminated paper as a raw material in a mold to shape it into a specific shape by thermal dehydration under pressure process.
