Abstract:
1. An electronic device that has at least one input device, the electronic device comprising: a main electrode pair arranged as the input device and configured such that inter-electrode distance varies in accordance with a pressing force; a first sub electrode pair arranged at a position different from the main electrode pair and configured such that inter-electrode distance varies in accordance with a pressing force; and a signal processor that monitors capacitance value of the main electrode pair and the first sub electrode pair and performs predetermined signal processing in accordance with the capacitance value that is detected, wherein the electronic device is a communication terminal, and the first sub electrode pair is disposed at a position where the first sub electrode is pressed by being in contact with a user's head, in a state in which a user of the communication terminal brings a casing close to an ear in order to communicate.
