Abstract

A capacitive touch sensor comprises a window panel and a capacitive sensor disposed under said window panel. Said capacitive sensor comprises a substrate, a first electrode pattern and a second electrode pattern formed in an intersecting direction with each other on an upper side of the substrate, and circuit wires selectively connected to the first electrode pattern and the second electrode pattern. Said second electrode pattern comprises a plurality of electrode pattern elements, which are disposed in a mutually separated state on both sides of the first electrode pattern in an intersecting direction and in a direction in which the first electrode pattern is extended, and said neighboring electrode pattern elements are electrically connected with each other by a bridge electrode pattern which is positioned therebetween and crosses the upper part of the first electrode pattern.
