A touch panel includes a first substrate, a second substrate, a slit, and a groove. 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 slit is provided in the first conductive layer and the second conductive layer and has an intersection or a terminal section. The groove section is provided to surround the intersection or the terminal section. This structure provides the touch panel that can have stable electrical connection and separation by a simple structure.
