PROBLEM TO BE SOLVED: To form a pallet made of a synthetic resin, in which since the wall thickness of each vertically swollen stripe portion is formed in substantially the same wall thickness as that of a peripheral wall other than the vertically swollen stripe portions, each vertically protruding stripe has no possibility of causing sink at its thick-walled portion due to the cooling in the manufacturing process of a pallet of a synthetic resin by injection molding like conventional girders formed by making the wall thickness of a peripheral wall thick, and which is hence stable in strength, rigidity and a product shape. SOLUTION: The pallet P made of a synthetic resin has girders 30, 40, 50, 80 and 90 which connect deck boards 10 and 20 to each other. In this pallet, vertically swollen stripe portions 70 are formed by allowing peripheral walls 30b and 80b at girder portions positioned at the corner parts of the pallet to be swollen from the inside of each girder toward the outside thereof, and the wall thickness t2 of each vertically swollen stripe portion is formed in substantially the same wall thickness as the wall thickness t1 of a peripheral wall other than the vertically swollen stripe portions.
