A scroll structure of a scroll compressor is provided to obtain improved surface flatness of an end plate of an orbital or stationary end plate by forming a height difference between inner and outer sides of the end plate, and to ensure stabilized operation of an orbital scroll while preventing leakage of refrigerant. A scroll structure of a scroll compressor comprises a disk-like end plate(11), and an involute-shaped wrap(12). The end plate is respectively disposed on the opposite sides. The wrap is respectively provided on the countering surfaces of the opposite end plates to define a compression chamber having smaller volume in the center while the wraps are meshing with each other. The inner side and outer side of the wrap defining the compression chamber have a predetermined height difference(t1), which is less than 0.02mm.
