PROBLEM TO BE SOLVED: To ensure the strength and to prolong the lifetime by preventing intrusion of gas into a resin gate part from occurring. SOLUTION: A synthetic resin pallet has an upper deck board 2 and a girder part and a lower deck board and a girder part. A plurality of reinforcing ribs 9 are provided on the girder part side of the upper deck board 2 to form a hollow part with gas being filled in the reinforcing ribs 9. A resin gate part for filling a molten resin is provided on a loading surface of the upper deck board 2, and a resin receiving part 8 flush with a back side of the upper deck board 2 is formed at the position of the resin gate part on the back surface side opposing the loading surface. The reinforcing ribs 9 are provided around the resin receiving part 8, and a recessed groove 18 is formed between the resin receiving part 8 and the reinforcing rib 9. The molten resin is filled in a mold of the upper deck board 2 from the resin gate part. When gas is then filled therein, intrusion of the gas flowing in the reinforcing ribs in the resin gate part of the resin receiving part 8 filled with high-temperature resin is prevented by the recessed groove 18.
