A thin input device is disclosed that is capable of simultaneously inputting rotational information and switching information. If a part of the human body H is rotated around a plurality of operating portions capacitance C is generated between the human body H and the respective electrodes, which are opposite to the human body H, in sequence. Therefore, a variation of the capacitance C corresponding to the respective operating portions is detected so as to obtain information on the rotational operation. In addition, if the operating portions are simultaneously tapped, the capacitances C of the electrodes are varied in sequence. Thus, simultaneous contact with the operating portions can be detected by detecting the variation of capacitance C.
