PROBLEM TO BE SOLVED: To provide a synthetic resin pallet capable of achieve strength, weight reduction and a core layer filling ratio of the pallet made of the synthetic resin with a good balance. SOLUTION: The pallet made of the synthetic resin is formed by welding mutually a girder part of an upper deck board and a girder part of a lower deck board. For the upper deck board, a plurality of the girder parts are connected with a top board 5 forming a loading surface, and a reinforcing rib 6 is provided between the girder parts. For the reinforcing rib 6a connected orthogonally to the central girder part, a skin layer 14 of a virgin resin is provided on the surface, a core layer 15 of a regenerated resin is provided in its inside, and a hollow part 16 made by gas injection is provided in the innermost layer. The hollow part 16 projects so as not to project into the top board 5 beyond necessity. The top board 5 consists of a skin layer and a core layer. The thickness W of the top board 5 at a part where the reinforcing rib 6 is provided is 2-5 mm, and the maximum thickness T at the root on the top board 5 of the reinforcing rib 6 is 5-30 mm, and the height H of the reinforcing rib 6 including the top board 5 is set in a range of 10-50 mm.
