PROBLEM TO BE SOLVED: To provide a touch panel device capable of improving a signal-to-noise ratio, and an input detection method thereof.SOLUTION: A driving signal supplier 200 drives simultaneously at least two of a plurality of driving signal electrodes TX1, ..., TXn by applying driving signals. The driving signal is controlled to include a plurality of time intervals in which the driving signal is applied to at least one of at least two driving signal electrodes simultaneously driven, and in which the driving signal is not applied to at least other of at least two driving signal electrodes simultaneously driven. The driving signal supplier 200 causes that a combination of the driving signal electrode to which the driving signal is applied in one of the plurality of time intervals and the driving signal electrode to which the driving signal is not applied in the one of the plurality of time intervals is different from a combination of the driving signal electrode to which the driving signal is applied in the other of the plurality of time intervals and the driving signal electrode to which the driving signal is not applied in the other of the plurality of time intervals. At least one among the driving signals which are simultaneously applied to the driving signal electrode has phase difference from the other driving signals. |
