Abstract
To detect a position on a screen with which even a thin nib is in contact, and improve operativity, visibility at the time of operation, and a feeling of use. A touch screen film 5 includes at least a transparent, conductive, thin film 7 which has a predetermined surface resistivity set to be within a range from 105.0 to 108.0 Ω/sq; when a pointing means 30 comes into contact with the film, a change in capacitance per unit area of 0.36 to 6.00 pF/mm2 occurs in a dielectric material 4 between a predetermined area including the contact position and the sensor electrode.
