A touch panel includes plural scanning electrodes, plural detection electrodes that are formed to intersect with the plural scanning electrodes, one or a plurality of layers being disposed between the plural detection electrodes and the plural scanning electrodes, plural holes that are arrayed apart from each other on each of the plural detection electrodes, and shaped into polygons each shaped to have five or more corners in a plan view, and plural dummy electrodes that are formed between the respective adjacent detection electrodes, made of the same material as that of the detection electrode, and electrically isolated from each other, in which the plural dummy electrodes are shaped into the polygons in a plan view.
