| Zusammenfassung: | A touch panel has excellent visibility and little waviness on respective elements even if the touch panel is exposed in a severe temperature or moisture environment. The touch panel includes an upper electrode sheet and a lower electrode board having respective transparent electrodes face to each other, and both of the sheet and the board are made of respective materials containing an identical main component to each other. In the touch panel, differences in dimensional changes due to the severe environment are restrained so as to be small. Therefore, waviness on the upper electrode sheet and warp of the lower electrode board scarcely occur, and the touch panel can maintain excellent visibility. |
