SOLUTION: An upper electrode sheet 1 having a transparent electrode on a transparent film, consisting of polyethylene terephthalate and a lower electrode sheet 2 having a transparent electrode on a transparent film consisting of polycarbonate are disposed facing opposite through a spacer 3 consisting of an insulator between the electrodes. A transparent holding board 5 consisting of a polycarbonate board is stuck via a transparent adhesive layer 4 to the lower surface of the lower electrode sheet 2 as a whole.</p> |
