Abstract

An indication instrument with improved illumination efficiency. The indication instrument has an indication panel (100), an indication plate (200) on which index parts (201) are disposed along the outer periphery of the indication panel (100), a pointer (11) for indicating the index parts (201), a drive source (7) for driving the pointer (11), and an indication plate light source (light source) (700) for illuminating the indication plate (200). The pointer (11) is routed around the rear of the indication panel (100) to reach the front of the indication plate (200). The indication instrument further comprises a frame (300) for joining to each other the indication panel (100), the indication plate (200), and the light source (700). An illumination chamber (R1) for guiding the light of the light source (700) to the indication plate (200) is formed in the frame (300).
