The present invention provides virtual keyboard which can be used at the same number of operations as on a conventional keyboard and can allow a natural input operation at a minimized load. The virtual keyboard comprises a liquid crystal display for displaying thereon a keyboard having special keys and general keys, a transparent pressure-sensitive panel superimposed on the display and a computing portion that, when a special key and a general key on a pressure-sensitive panel are pushed at a time, detects the coordinate of a middle point between the two pushed positions from outputs of the pressure-sensitive panel, calculates a general key position from the special key point and the middle point and outputs a code corresponding to that position.
