ABSTRACT:
An input apparatus of the resistive type that is thinner and more durable is provided. The apparatus includes a first substrate having a conductive film on which a plurality of slits are formed in stripes, and a second substrate spaced apart from the first substrate at a fixed distance to face the surface of the first substrate implementing the conductive film. This second substrate has a conductive film formed on the surface facing the conductive film of the first substrate. A driving voltage is applied between two predetermined points on the conductive film formed on the first substrate. An electric potential of the conductive film formed on the second substrate is detected when the two conductive films come into contact.
