This loop antenna is provided with: an insulating substrate; an antenna portion that is a conductor provided on the substrate and includes a first feeding portion, a second feeding portion, and an antenna mesh portion having a mesh structure and forming a loop shape by connecting the two feeding portions to each other; and a dummy pattern part portion that is a conductor having a mesh structure and provided in a region surrounded by the antenna portion, and is isolated from the antenna portion. The dummy pattern portion has at least one cut portion that cuts a path included in the mesh structure.

Loop antenna

In a touch panel in which a sensor electrode array, frame wiring set that is located outside the sensor electrode array and connected to the sensor electrode array, and a first outer ground wiring line located outside the frame wiring set are formed on a transparent substrate of the touch panel, shielding wiring covering the frame wiring set is provided, with an insulating layer placed between the frame wiring set and the shielding wiring, and a second outer ground wiring line is provided outside the shielding wiring. The shielding wiring is connected to a ground wiring line included in the frame wiring set through a hole formed in the insulating layer and is insulated from the second outer ground wiring line.

Touch panel having high resistance to static electricity
