PROBLEM TO BE SOLVED: To compensate degradation in strength and rigidity of a corner beam/intermediate beam lower coupling bar as the thickness of a lower deck is made thinner than that of an upper deck, and to increase strength and rigidity of a synthetic resin pallet. SOLUTION: The synthetic resin pallet has a corner beam 1, an intermediate beam 2 and a center beam 3. The thickness t2 of the lower deck D2 is formed to be thinner than the thickness t1 of the upper deck D1. The number of crossing bars 5b constituting the corner beam-intermediate beam lower coupling bar 5 for coupling the lower end of the corner beam with the lower end of the intermediate beam is made larger than the number of crossing bars 4b constituting a corner beam-intermediate beam upper coupling bar 4 for coupling the upper end of the corner beam with the upper end of the intermediate beam.
