To provide a pallet whose front face part and back face part of a corner outer peripheral end part are balanced in strength with simple structure, and whose front face part and back face part of a corner part are prevented from deforming or damaging without damaging loaded materials such as a loaded corrugated cardboard.

A synthetic resin pallet 5 having a square shape in a plane view is constituted by arranging girder parts 3 which have hollow inside and front and back with opening parts 20 for discharging a metallic mold between the front face part 1 and back face part 2, and by forming fork inserting holes 4 between the adjacent girder parts 3. In this case, a corner outer end face board part 21 on the front face side and a corner outer end face board part 22 on the back face side are formed on the each front face part 1 and the back face part 2 of the corner outer peripheral end part of the girder part 3 which is positioned at the corner part of the pallet 5 having a square shape in a plane view.
