To provide a terminal device facilitating calibration work.

The terminal device includes: a display unit (28) rotatably supported against a device body; an input panel (27) disposed on a display surface of the display unit for detecting information about the coordinates of a position where an object makes contact; a reference point contact means (40) securely disposed on the device body and capable of contacting at least two protrusions (41, 42) serving as reference points for the input panel stored in a fixed position of the device body; and a coordinate information correction means (29) for obtaining information about the coordinates of positions where the protrusions of the reference point contact means make contact, and correcting the difference of the coordinate information detected by the input panel, according to the coordinate information.
