Abstract: This disclosure relates to a pallet includes a first board, a second board, a first elastic component and a second elastic component. The first elastic component and the second elastic component are disposed between the first board and the second board, and the second elastic component is closer to an edge of the second board than the first elastic component. The second elastic component has a density higher than that of the first elastic component.
