The operation device 1 has: a switch array 20 in which operation switches (21, 22, 23, 24) are arranged; electrostatic detection sensors (first electrostatic detection sensor 12, first electrostatic detection sensor 14) which are disposed above or below the switch array 20, thereby detecting two-dimensional coordinate values when an object to be detected, such as a finger of an operator, has come close thereto; and a control unit 300 equipped with a determination part for determining whether or not the object to be detected has come close to any one of the operation switches of the switch array 20 on the basis of a detection result of the electrostatic detection sensors.
