The present invention is to provide an indicating instrument useful to a speedometer for a vehicle. An internal driving unit (2) is secured to a printed circuit board (1), and a cylindrical rotating shaft (6) is carried by bearings (4, 5) of the internal driving unit (2). A pointer (9) is secured to the rotating shaft (6) and rotated via the rotating shaft (6) by the internal driving unit (2). A light emitting diode (12) is disposed inside the rotating shaft (6) and secured to the printed circuit board (1). Light emitted by the light emitting diode is collected by a light collecting portion (9a) of the pointer (9), reflected by a reflecting portion (9b) and illuminates the pointer (9).
