Provided is a conductive member for a touch panel, a touch panel, and a touch panel display device capable of accommodating a first and a second lead wire in a narrow region. A conductive member for a touch panel includes a first conductive layer disposed on a transparent insulating substrate; an insulating layer disposed on the first conductive layer; and a second conductive layer disposed on the insulating layer. The first conductive layer has a plurality of first touch detection electrodes, and a plurality of first lead wires led from the plurality of first touch detection electrodes. The second conductive layer has a plurality of second touch detection electrodes, and a plurality of second lead wires led from the plurality of second touch detection electrodes. At least a part of the first lead wire and at least a part of the second lead wire overlap each other in plan view.
