Abstract
An operation detection sensor is provided and an electronic apparatus is provided that detect an operation on an operation target regardless of a waveform state of an output voltage of a sensor. The operation detection sensor includes a piezoelectric element, a voltage detection circuit that detects a voltage generated in the piezoelectric element, and a calculation unit that obtains a reference voltage by averaging detection voltages of the voltage detection circuit, and detects an operation on an operation target when a state in which a voltage difference between the reference voltage and the detection voltage is a predetermined value or more continues for a predetermined time or more.
