PROBLEM TO BE SOLVED: To provide a frame structure of a panel plate capable of commonly using both thin panel plates and thick panel plates in one frame. SOLUTION: The frame 22a comprises an outer peripheral part 33 of flat plate-shape in cross section and an inner peripheral part 36 projected from the lateral center of the outer peripheral part 33 inward and having an inwardly opening groove part 40 at the lateral center. The peripheral edge of the thin panel plate can be fitted to the groove part 40. The inner peripheral part 36 is formed to be fitted to the peripheral edge opening part M of the thick panel plate 20 comprising a core material 20a having a thickness approximately the same as the width of the inner peripheral part and surface plates 20b and 20c far larger than the core materials 20a laminated on both sides of the core material 20a, and both the thin panel plate and the thick panel plate 20 can also be fitted to one common frame.
