| 1. An optically transparent touch panel comprising:
an upper substrate having an upper conductive layer formed on a lower surface thereof;
a lower substrate having a lower conductive layer formed on an upper surface thereof to confront said upper conductive layer
with a predetermined space therebetween; and
a spacer disposed between outer peripheries of said lower surface of said upper substrate and said upper surface of said lower
substrate, said spacer bonding together said upper substrate and said lower substrate, wherein
said spacer has a modulus of elasticity of at least 1.0×104 Pa and lower than 8.0×104 Pa.
