To increase the rigidity of a pallet while keeping the light-weight property of the overall pallet by a method wherein a plurality of first connecting bridges to connect an intermediate beam and a central beam are respectively provided on the top and the bottom between the intermediate beam and the central beam, and at the same time, second connecting bridges are provided between the first connecting bridges, and between a deck bridge and the first connecting bridge.

A pallet 10 made of a synthetic resin is constituted by connecting an upper surface deck 11 and a lower surface deck by a plurality of beams 20, and the plurality of beams 20 are constituted of corner beams 21 which are provided at four corners of the pallet 10, intermediate beams 22 which are provided at intermediate locations between respective corner beams 21, and central beams 23 which are provided at the center of the pallet 10. Then, between the upper end parts of respective intermediate beams 22 and the central beams 23, a plurality of first connecting bridges 41A on the upper side, which connect the intermediate beams 22 and the central beams 23, are provided, and a plurality of the first connecting bridges on the lower side are provided between the lower end parts of them. Also, between the upper side first connecting bridges 41A, and between a deck bridge 44A and the first connecting bridge 41A, a thin flat plate-form second connecting bridge 42 which is arranged in the direction being orthogonal with the first connecting bridge 41A and connects those bridges, is provided.
