A position detection method in a touch panel that includes a first resistance film having first and second electrodes provided one on each end in a first direction and a second resistance film having third and fourth electrodes provided one on each end in a second direction orthogonal to the first direction, the position detection method including calculating a distance between 2 contact points in the first direction by measuring a potential of the first electrode in a state where a power supply voltage is applied to the first electrode and the second electrode is grounded, calculating a distance between 2 contact points in the second direction by measuring a potential of the third electrode in a state where a power supply voltage is applied to the third electrode and the fourth electrode is grounded, and correcting the distance between the 2 contact points in the first direction obtained by the potential of the first electrode in accordance with the distance between the 2 contact points in the second direction obtained by the potential of the third electrode. |
