1. An electrostatic capacitance input device comprising:
an input region of a substrate, in which a plurality of input position detection electrodes are provided;
a plurality of wires that are electrically connected to the plurality of input position detection electrodes and extend outside the input region of the substrate;
a shield electrode that overlaps the wires on the input operation side; a flexible wiring board including
a plurality of flexible wiring board internal wires that are electrically connected to the plurality of wires outside the input region of the substrate, and
a flexible wiring board shield layer formed around the flexible wiring board internal wires; and
shielding wires for applying a shield potential to the flexible wiring board shield layer and the shield electrode,
wherein the shield potential applied to the flexible wiring board shield layer and the shield electrode has the same waveform and phase as a position detection signal supplied to the input position detection electrodes.
