Abstract: The electrostatic capacitance detecting device includes a first substrate; a detection electrode provided on a front-side surface of the first substrate to detect a proximity of an operating body to an operating face; a stray capacitance coupling conductor provided in a direction with respect to the first substrate, the direction being opposite to a direction of the detection electrode with respect to the first substrate; a first peripheral electrode provided on the front-side surface of the first substrate to surround the detection electrode; and a plurality of lateral electrodes provided side by side to surround the detection electrode, the plurality of lateral electrodes extending along a thickness direction of the first substrate and connected to each of the first peripheral electrode and the stray capacitance coupling conductor.
