Capacitance sensor which can provide sufficient capacitance value variation near edge

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;
• I 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;
• wherein the first electrically conductive lines respectively comprises a plurality of first electrically conductive blocks, wherein the second electrically conductive lines respectively comprises a plurality of second electrically conductive blocks;
• wherein at least one of the first electrically conductive line further comprises a first edge electrically conductive block;
• wherein the first electrically conductive blocks are rhombus-shaped, and the second electrically conductive blocks are rhombus-shaped or triangular-shaped;
• wherein the first edge electrically conductive block comprises a triangular electrically conductive block and an extension block, wherein the first edge electrically conductive block overlaps with the extension block;
• wherein the second protruding part surrounds the extension block.
