PURPOSE:To prevent electric charge from being accumulated due to static electricity, etc., by energizing between the surface and the rear plane of an armor panel easily and surely, by unifying them. CONSTITUTION:The titled device is constituted by combining a main frame 2, the armor panel 7 unifying its surface and rear plane, the joint part 9 of a surface and a rear plane panels, an external electrode 4, and a printed circuit board 5. In such a case, since a unified panel 7 is the one in which the surface and the rear plane panels are formed with a sheet of a metallic panel, the surface panel can be kept at the same potential as that of the rear panel. In such a way, no specific mechanism targeted to energize between the surface and the rear plane panels is required, and energizing can be surely and easily performed, and the accumulation of the electric charge due to the static electricity can be prevented from being generated, and it is possible to prevent the malfunction and the damage of a semiconductor device in a semiconductor device card from being generated.
