Abstract:
The invention provides a touch panel capable of effectively preventing a distortion of an electric potential distribution, thereby increasing an input region of the touch panel. A touch panel including a resistive layer formed on one of surfaces of a substrate and a frame-shaped electrode portion 21 provided along four sides of the resistive layer, wherein each side of the frame-shaped electrode portion 21 is constituted in a broken line pattern having a first split electrode 25a disposed on both ends respectively and a plurality of second split electrodes 25b disposed between the first split electrodes 25a, second resistance values R_i between the second split electrodes 25b are set to be equal to each other, and a first resistance value R_s between the first split electrode 25a and the second split electrode 25b which is adjacent to the first split electrode 25a is different from the second resistance value R_i.
