An input device comprising: a thick upper transparent electrode base member provided on a first surface with an upper transparent electrode group that includes a plurality of upper transparent electrodes (U1-U4) each having a rectangular shape and a longitudinal direction parallel to an X axis, and bus bars provided at, at least, one of the ends in the longitudinal direction of the upper transparent electrodes; and a lower transparent electrode base member provided on a first surface with a lower transparent electrode group that includes a plurality of lower transparent electrodes (L1-L6) each having a rectangular shape and a longitudinal direction parallel to a Y axis, and bus bars provided at, at least, one of the ends in the longitudinal direction of the lower transparent electrodes, the surface provided with the lower transparent electrode group of the lower transparent electrode base member and the surface provided with the upper transparent electrode group of the upper transparent electrode base member facing each other and being bonded together at peripheral edges; the input device further comprises a transparent pressure-sensitive conductive layer formed on a region containing the transparent electrode group on one of the surface provided with the upper transparent electrode group of the upper transparent electrode base member and the surface provided with the lower transparent electrode group of the lower transparent electrode base member; characterized in that the input device is not provided with dot spacers, instead a transparent liquid-form intermediate layer is further interposed between the pressure-sensitive conductive layer formed on the one of the transparent electrode base members and the region containing the transparent electrode group of the remaining one of the transparent electrode base members, wherein the transparent liquid-form intermediate layer is configured by acrylic-based, silicone-based, fluorine-based, or alcohol-based inert liquid; and in that the transparent liquid-form intermediate layer is movable and the transparent pressure-sensitive conductive layer configured such that, when pressing force is applied to a second surface of the upper transparent electrode base member opposite to the first surface of the upper transparent electrode base member, the applied force causes quantum tunneling current to flow between pressure-sensitive particles scattered in the pressure-sensitive conductive layer, thereby making the upper transparent electrode and the lower transparent electrode right below a pressed point to be conducted with each other, and the input device detecting position coordinating where the force is applied along the second surface of the upper transparent electrode base member. a thick upper transparent electrode base member provided on a first surface with an upper transparent electrode group that includes a plurality of upper transparent electrodes (U1-U4) each having a rectangular shape and a longitudinal direction parallel to an X axis, and bus bars provided at, at least, one of the ends in the longitudinal direction of the upper transparent electrodes;
