Abstract
A capacitive sensor has first electrodes, a second electrode, and a third electrode, which are disposed at places where a manipulating body that is part of a human body such as a finger is detected. The capacitive sensor also has a capacitance detecting means and a deciding means. The deciding means identifies the number of manipulating bodies and directions (positions) according to the capacitances of the first electrodes, second electrode, and third electrode.
