Abstract
An electrostatic capacitance detection device includes: an electrostatic capacitance sensor; and a control device that controls the electrostatic capacitance sensor, wherein the control device has a plurality of detection modes for detecting a capacitance change amount corresponding to a change amount of electrostatic capacitance of the electrostatic capacitance sensor, detects the capacitance change amount in each of the plurality of detection modes, and determines presence or absence of contact or approach of an object to the electrostatic capacitance sensor based on the capacitance change amount.
