Abstract
A touch panel including an upper substrate (4A) consisting of a soft film having an upper resistor film (51) and a lower substrate of a hard plate having a lower resistor film, which are bonded together to face each other. The touch panel provides a detection output representing the position of contact between the upper resistor film (51) and the lower resistor film as two-dimensional coordinate values. Either the upper resistor film (51) or the lower resistor film or both are of a comb shape having a plurality of resistive lines with a common connector (41) at one end.
