Abstract: A first mesh pattern (13) of a touch sensor (1) includes first cells (15) in a diamond shape with an acute angle (A1). A second mesh pattern (16) of the touch sensor (1) includes second cells (18) in a square shape. The acute angle (A1) ranges from 50° to 65°. One of second thin wires (17) of each second cell (18) and the longer diagonal line 15a of associated one of the first cells (15) form an angle A2 ranging from 15° to 75° in a plan view.

Abstract: A touch sensor includes a substrate with a first surface, and a plurality of first electrodes on the first surface of the substrate in a view area. The first surface of the substrate includes a plurality of bottomed grooves extending linearly. Each first electrode includes a plurality of fine lines including a conductive material buried in one of the grooves. Each fine line includes a bottomed recess recessed from the first surface toward the bottom surface of each groove.
