ABSTRACT:
A pointer for measuring instruments includes a fixing portion mounted on a drive shaft of a drive and an indicating portion supported on the fixing portion and extending therefrom in a direction perpendicular to an axis of the drive shaft. The indicating portion includes an EL element having a light-emitting surface extending over a substantially entire length of the indicating portion in the direction perpendicular to the drive shaft axis, at the light-emitting surface light being substantially uniformly distributed at least in the direction perpendicular to the drive shaft axis; a light-transmitting protective body covering at least the light-emitting surface; and an indicating tube. The surface of the portion of the indicating tube confronting at least the above light-emitting surface is arcuated in a circumferential direction of the direction perpendicular to the drive shaft axis. The pointer for measuring instruments is three-dimensionally illuminated with entirely uniform brightness, of high practical utility and producible at a low cost.
