摘要：
A coordinate input apparatus which can reliably specify a coordinate component (a position coordinate) of a selected position without a complicated structure irrespective of use conditions is provided. A coordinate input apparatus includes a capacity detecting portion which detects capacitance, wherein the coordinate input apparatus specifies a coordinate component of a selected position on the basis of a change in capacitance detected by the capacity detecting portion, and the capacity detecting portion includes a first conductive layer, an insulating layer which is formed on the first conductive layer, and a second conductive layer which is formed on the insulating layer in a mesh shape, and has a predetermined potential difference between the second conductive layer and the first conductive layer.
