PURPOSE:To obtain sintered parts which are improved in the accuracy of the flatness in the parts of powder compacted parts where said parts face a medium for transportation by transporting the powder compacted parts protected with spacers on the medium for transportation to a sintering furnace and sintering the parts. CONSTITUTION:The power compacted parts 1 are held by the spacers 2 and are imposed on the medium 3 for transportation which is a meshed belt. The spacers 2 can minimize the dispersion in the flatness of the parts of the parts 1 where said parts face the medium 3. Said spacers are formed of materials such as refractories, steel materials and sintered materials. Since the spacers 2 are inserted between the parts 1 and the medium 3, the parts 1 can be supported at the same holding point. The width of the variance in the deflection of the parts of the parts 1 where said parts face the medium 3 is, therefore, decreased. The accuracy of the flatness in the parts of the parts 1 after sintering where said parts face the medium 3 is improved to the higher accuracy than before sintering by intentionally changing the size of the spacers 2 to meet the shape of the parts 1.
