PROBLEM TO BE SOLVED: To provide an input device capable of performing an input operation without generating any feeling of incompatibility even when the input device is operated with one finger.SOLUTION: The input device for enabling a user to input operation conditions to a predetermined device by operating the surface of a panel 110 with a finger includes: an extension part 120 extending from the back side to surface side of the panel 110, and having a wall part 121 erected with respect to the panel 110; a plurality of sensors 140 arranged inside the wall part 121 in a peripheral direction for generating a position signal showing the position of the finger when the sensors are operated with the finger outside the wall part 121 in the peripheral direction; and a control part 160 for detecting the position signal on the basis of a predetermined initial threshold, and for controlling an input control value to a predetermined device in accordance with the detected position signal, and for, when determining that the sensitivity of the position signal deteriorates, reducing the initial threshold. |
