PROBLEM TO BE SOLVED: To provide an vibration-welded pallet capable of reducing the weight, and achieving the consistent welding of outer peripheral wall halves, and having high welding strength of the outer peripheral wall halves and excellent appearance. SOLUTION: A cylindrical girder half 2 has an outer peripheral wall half 8 and a plurality of partition wall halves 9 for partitioning a part surrounded by the outer peripheral wall half 8. The wall thickness of the partition wall half 9 crossing the oscillating direction (b) of the oscillation welding out of the plurality of partition wall halves 9 is set to be larger than that of the partition wall half 9 parallel to the oscillating direction (b) of the oscillation welding, and also set to be substantially equal to the wall thickness of the outer peripheral wall half 8, or larger than that of the outer peripheral wall half 8. Fore ends of the outer peripheral wall half 8 are integrated by the oscillation welding to form an outer peripheral wall 10 of the cylindrical girder part 6. Fore ends of the plurality of partition wall halves 9 are integrated with each other by the oscillation welding to constitute a plurality of partition walls 11 for partitioning the inside of the outer peripheral wall 10 by both partition wall halves 9.
