Abstract

Provided is a capacitive coupling type touch panel, including: a plurality of coordinate detection electrodes (XP 1 , XP 2 , YP) for detecting X-Y position coordinates; a first substrate including the plurality of coordinate detection electrodes; and a second substrate ( 6 ) disposed to be opposed to the first substrate, in which: the capacitive coupling type touch panel further includes, between the first substrate ( 1 ) and the second substrate ( 6 ): a conductive layer (ZP) having conductivity; a nonconductive layer ( 8 ) supporting the conductive layer; a plurality of nonconductive spacers ( 4 ) that are formed at intervals in a plane direction of the first substrate and the second substrate; and an elastic layer ( 5 ) that is lower in rigidity than the first substrate, the second substrate, and the plurality of nonconductive spacers.

Claims (29)
