Abstract
A touch panel includes a first substrate, a second substrate, and a plurality of insulating grooves. The first substrate has a first conductive layer, and a plurality of first electrodes that extend from both ends of the first conductive layer and that have first electrode lead sections. The second substrate has a second conductive layer, and a plurality of second electrodes that extend form both ends of the second conductive layer and that have second electrode lead sections. The insulating grooves are provided in at least one of the first conductive layer and the second conductive layer between any one of the first electrode lead sections and the second electrode lead sections. This structure provides a touch panel having a smaller pitch between the first electrode lead sections or between the second electrode lead sections and having stable electrical insulation and connection.
