Patent ID: 8269724

Claim:
A coordinate input apparatus, comprising: a capacitance detecting portion which detects capacitance, wherein the coordinate input apparatus specifies a coordinate component of a selected position based on a change in capacitance detected by the capacitance detecting portion, wherein the capacitance detecting portion comprises: a first conductive layer, an insulating layer uniformly formed on and contacting the first conductive layer, the insulating layer having a substantially constant thickness and being free of openings, and a second conductive layer formed on the insulating layer and contacting the insulating layer, wherein one of the first conductive layer and the second conductive layer is a patterned sheet formed in a mesh shape and the other of the first conductive layer and the second conductive layer is a single continuous unpatterned sheet free of openings, wherein sizes of through holes in the mesh shape of the patterned sheet gradually increase from an end portion to a central portion of the patterned sheet and a predetermined potential difference exists between the second conductive layer and the first conductive layer.
