Said pallet made of synthetic resin is used for transporting and loading various goods. It is fitted with a covering plate and a fork inserting opening, as well as building blocks on both sides of said fork inserting opening. Its particularity resides in that the pallet is divided into several weld-joined components, which are preformed so that their weld-joining faces are made as mutually parallel surfaces in the same direction. Besides, the above-mentioned weld-joined components are made into at least two types consisting of two identically formed weld-joined components constituting both sides of the pallet, as well as a medial weld-joined component constituting the middle part of the pallet. These weld-joined components are assembled together, and the covering plate as well as the building blocks are of hollow construction. When in use, at least the upper surface of the upper covering plate is formed into a sealed smooth surface.
