A resistive touch panel comprising: a first conductive film divided into regions in a matrix having rows and columns, the regions are insulated from each other; a second conductive film facing and located away from the first conductive film; a first pair of electrodes (6, 8) being located in hems along two of four sides of the second conductive film and located at opposite edges of the second conductive film; a second pair of electrodes (10, 12) being located in hems along the other two of the four sides of the second conductive film and located at opposite edges of the second conductive film; and a control unit configured: in each of the regions, to determine whether or not the first conductive film contacts with the second conductive film in the region; and in the or each region in which it is determined that the first conductive film contacts with the second conductive film, to detect one of an X-coordinate or a Y-coordinate of a point where the first conductive film contacts with the second conductive film by applying a voltage to the first pair of electrodes (6, 8); after the determining in each of the regions and the detecting in the or each region in which the first conductive filmn contacts with the second film, to discharge the voltage applied to the first pair of electrodes (6,8); and after the discharge, to additionally detect the other of the X-coordinate or the Y-coordinate in the or each region in which it is determined that the first conductive film contacts with the second conductive film, by applying a voltage to the second pair of electrodes (10, 12), and to discharge the voltage applied to the second pair of electrodes (10, 12) after the additional detecting in the or each region in which the first conductive film contacts with the second conductive film; wherein the number of discharges is two regardless of the number of regions in which it is determined that the first conductive film contacts with the second conductive film. a first conductive film divided into regions in a matrix having rows and columns, the regions are insulated from each other;
