PROBLEM TO BE SOLVED: To provide an operation detection device configured to reduce processing load and to improve the accuracy of a detection position.SOLUTION: An operation detection device 1 includes: first and second electrodes 11, 12 arranged below an operation surface 100 to be operated, and spaced from each other along an X-axis direction, as shown in Fig.2 (a) and (b); a sub-electrode 14, as a third electrode, insulated from the first and second electrodes 11, 12 and arranged closer to the operation surface 100 than the first and second electrodes 11, 12; a detection unit 18 which is electrically connected to the first and second electrodes 11, 12 to detect a detection value based on finger operation on the operation surface 100; and a calculation unit 20 which calculates a detection position where a finger is detected on the basis of the detection value detected by the detection unit 18. |
