PROBLEM TO BE SOLVED: To provide an indicator-type measuring instrument having a simple structure capable of improving the illumination efficiency, when illuminating an indicator panel from its surface side. SOLUTION: The indicator-type measuring instrument is equipped with an indicator 7; the indicator panel 6 on which an index section 62 being an object to be indicated by the indicator 7 is disposed; and a light source L3, which is disposed behind the indicator 7 and at the periphery of its rotational center. Furthermore, a reflecting surface 74 is formed on the indicator 7, which tilts so as to move away from the rotational center, in accordance with increasing of the distance from the light source L3 and reflects light from the light source L3 toward the surface of the indicator panel 6. A circular conical surface is preferably used as the reflecting surface 74. COPYRIGHT: (C)2006,JPO&NCIPI
