PROBLEM TO BE SOLVED: To provide a touch panel device configured to require no battery for a wireless electronic pen.SOLUTION: A touch panel device 1 includes: a capacitive touch panel 11 to be touch-input with an electronic pen 30; and a power supply section 20 which supplies electric power for driving the electronic pen from detection electrode 18, 19 on the touch panel, via at least two drawing drive electrodes 40a, 40b arranged in the electronic pen, to the electronic pen. Preferably, the power supply section drives the detection electrodes on the touch panel so that a positive electrode and a negative electrode corresponding to a distance between the drive electrodes may appear.SELECTED DRAWING: Figure 5 |
