PURPOSE: A pallet is provided to improve strength while being formed by synthetic resin corrugated cardboard. CONSTITUTION: A pallet(10) is formed by an upper plate(20), a lower plate(25), and a spacer(30). Herein, the spacer is integrally formed with support bars(32) of synthetic resin corrugated cardboard. After producing the support bars by folding the cardboard, the support bars are assembled to form the spacer. The upper plate and the lower plate formed by the synthetic resin corrugated cardboard are located on upper and lower portions of the spacer. Then, the plates are combined in a supersonic wave method to complete the pallet. Herein, the support bars are formed in orthogonal direction to lengthwise direction of a support separate wall(24). Then, the support separate wall connects the upper plate and the lower plate. Herein the support separate walls are formed in crossing each other to utilize strength characteristic of the corrugated cardboard.
