Abstract
A display/input device is provided which includes a position sensor on which an electrode pattern in grid form is arranged, the position sensor being for specifying a position of an operating tool by detecting a capacitance changing at a contact part or a proximity part at a time the operating tool is made to contact the electrode pattern or is brought into proximity of the electrode pattern, and an outer frame portion forming an outer frame of a display screen provided with the position sensor. A boundary of an area where the position of the operating tool can be specified by the position sensor despite a non-presence of the electrode pattern is visually or haptically indicated at the outer frame portion.
