Conductive film and touch panel

A touch panel comprising:

• a conductive film:
• a protective layer which is provided on the conductive film to protect the conductive film;
• and
• a display device which has a display unit,
• wherein the conductive film includes:
• a transparent substrate;
• a detecting portion which is provided on at least one surface of the transparent substrate and is provided with a mesh pattern formed of thin metallic wires;
• and
• a peripheral wiring portion which is provided on at least one surface of the transparent substrate and is electrically connected to the detecting portion, and
• wherein in a case where a region where the detecting portion is provided is set as a first region and a region other than the first region is set as a second region in the transparent substrate,
• a wire width change region is present in at least a part of a boundary region including a boundary line between the first region and the second region,
• in the wire width change region, a wire width of the thin metallic wire of the detecting portion is larger than a reference wire width of the thin metallic wire at a center of the first region, and is continuously increased along a direction from the first region to the second region,
• the first region is superposed on a display region of the display unit such that the conductive film is disposed on the display device, and
• the wire width change region is present on an edge portion of the display region of the display unit.
