To provide a small input device superior in operability, which uses what is called a tablet system.

The input device uses the pointing device of the tablet system and it has a tablet 10 being an input operation face and an actuator part 11 which is brought into contact with the input operation face with the depression operation of the finger of a user. The actuator part 11 is supported by the supporting member 12 of plastics or the like against the input operation face so that it is brought into contact with any directions corresponding to the depression operation, for example. The pointing device of such constitution can be made this and small. Since a precise input operation is easily realized only by operating the actuator part 11, the input device with superior operability is provided.
