Abstract
A resistive film type touch panel includes a transparent insulating film, a plurality of upper electrodes, and a plurality of routing wires. The plurality of upper electrodes are formed on the lower surface of the transparent insulating film and are arranged in a direction, and includes a group of the electrodes electrically connected with each other. The electrical combinations of the detection electrodes adjacent with each other in the direction of a planned simultaneous detection number are different from one another. The plurality of routing wires extend from the plural upper electrodes, and are formed in a frame area outside of the plurality of upper electrodes on the lower surface. Thus, the number of the electrodes is increased in order to improve the resolution, while also miniaturizing the touch panel.
