A pallet includes columns, an upper deck, and a lower deck. The upper deck links upper ends of the columns such that upper surfaces of the columns and upper deck form an upper deck surface. The lower deck links lower ends of the columns such that lower surfaces of the columns and lower deck form a lower deck surface. Fork insertion structures receive forks of a lift apparatus inserted thereto from four sides of the pallet. Outer circumferential projections are formed along a peripheral edge of the upper deck surface, including an extended portion extending outward from the peripheral edge, and a support portion protruding upward from the extended portion. The support portion has a first height in an insertion-corresponding region, and a second height in a general region, the first height being equal to a thickness of the lower deck, the second height being greater than the first height.
