ABSTRACT:
A coordinate input device includes a coordinate input unit which performs a coordinate input operation by sliding an operating member on an operation surface which is formed in a convex shape, a concave shape, or the shape of a polyhedron. More specifically, the coordinate input device includes a capacitive sensor substrate formed by laminating two electrode layers with an upper substrate (dielectric layer) therebetween, each electrode layer including a plurality of electrodes arranged in a striped pattern. In addition, the coordinate input device also includes the operation surface formed in a convex (or concave) shape which is used for performing a coordinate input operation by sliding the operating member thereon.
