Abstract
A capacitance sensor, comprising: a plurality of first electrically conductive lines, wherein at least one side of two adjacent ones of the first electrically conductive lines respectively has a notch and the notches are opposite to each other; a second electrically conductive line, crossed with the first electrically conductive lines, wherein the second electrically conductive line further comprises a second protruding part protruding from the second electrically conductive line; wherein the second protruding part is located between the notches; wherein a distance between the two adjacent ones of the first electrically conductive lines at the side is larger than or equal to a maximum distance between the notches. Such capacitance sensor can provide sufficient capacitance value variation even at an edge region.
