Abstract
A resistive film type touch panel is configured to reduce damage that is caused by contact between electrodes in a resistive film type touch panel that includes a plurality of first electrodes and a plurality of second electrodes that extend in direction that intersect one another. The resistive film type touch panel includes a plurality of lower side electrodes and a plurality of upper side electrodes. The lower side electrode extends in the Y direction. The upper side electrode X1 extends in the X direction, which intersects the Y direction, and opposes the plurality of lower side electrodes. Each lower side electrode includes an electrically conductive layer and protective layers, and a silver layer and a carbon layer extend in the Y direction. The protective layers are formed on edge parts on both sides in the width direction of the electrically conductive layer such that they extend in the direction.
