1. An input device comprising:
- an input section including a coordinate input sheet which includes a conductive pattern, the input section allowing a coordinate input by using a change in electrostatic capacity in response to a finger movement and a push-input onto a display section on which a mark is shown;
a substrate having a conductive unit disposed under the input section with a space therebetween;
a push-switch section disposed on the substrate at a place corresponding to the display section; and
an insulating resin layer containing sufficient air to reduce the affect of the conductive unit on the electrostatic capacity of the coordinate input sheet, said insulating resin layer being disposed between the substrate and the input section, wherein;
a height of the insulating resin layer is set so that an upper surface of the insulating resin layer supports a bottom face of the coordinate input sheet so that the coordinate input sheet is held at a given distance from the conductive unit by the insulating resin layer when the coordinate input is performed with the finger moving on the input section while touching the input section, andcompressible amount of the insulating resin layer is greater than a stroke of the push-switch section.

Abstract
An input device includes an input section formed of a display sheet and a coordinate input sheet, and a switch section allowing a push-input and placed on a substrate at a place corresponding to a display section of the display sheet. A foamed layer containing air and working as an insulating resin layer is placed between the input section and the substrate. The input section is supported via the foamed layer.
