1. A wide range-inputable touch panel of analog resistance film type, the touch panel comprising:
- a first transparent insulating base;
a pair of first bus bars arranged in parallel to each other on one surface of the first transparent insulating base;
a first transparent electrode having at least a first input area between the first bus bars;
a second transparent insulating base;
a pair of second bus bars arranged in parallel to each other on one surface of the second transparent insulating base; and
a second transparent electrode having a second input area between the second bus bars that corresponds to the first input area,wherein the first transparent insulating base, the first bus bars, and the first transparent electrode compose a first conductive panel, and the second transparent insulating base, the second bus bars, and the second transparent electrode compose a second conductive panel,wherein the first transparent electrode further comprises a third input area that is adjacent to the first input area and that corresponds to at least one bus bar of the pair of second bus bars,wherein the touch panel further comprises;
an insulating adhesive layer that sticks together circumferential portions of the first and the second conductive panels facing each other so that the first and the second bus bars are arranged rectangularly, wherein the insulating adhesive layer has space sections provided between at least the one bus bar of the pair of second bus bars and the third input area of the first transparent electrode so as to allow the one bus bar and the third input area to be brought into electrical contact with each other by a press; and
first and second routing circuits connected respectively to the first and the second bus bars on the conductive panels,wherein the space sections are spaces formed in the adhesive layer cut out from an outer edge side thereof.
