Abstract: A touch panel device (11) includes a panel main body (21) including a plurality of first electrodes (X) extending parallel to one another and a plurality of second electrodes (Y) intersecting with the first electrodes (X), and a detection section (31). The detection section (31) includes a transmission section (33) for sequentially applying a driving signal to the first electrodes (X), and a current-voltage conversion section (35) configured to scan the second electrodes (Y) and convert a current flowing through the second electrode (Y) to a voltage signal, an AD conversion section (36) configured to sample the voltage signal and convert it to digital data, and a touch determination section (37) for determining a touch position from the converted digital data. The AD conversion section (36) samples the induced signal for a sampling period which occurs after a preset time which is determined for each of the first electrodes (X) elapses since the application of the driving signal and which includes a peak of a waveform of the induced signal.
