<p>An upper electrode (6G) for a peripheral switch is in contact with a lower electrode (5G) for the peripheral switch, and a pressure-sensitive conductive member (25) is arranged in a through hole (10) of a substrate adhesive layer (17), so that the force acting on the peripheral switch (12) is transmitted through the upper electrode substrate and the upper electrode to the pressure-sensitive conductive member to flow a current, and conduction between the upper electrode and the lower electrode can be achieved.</p>
