PROBLEM TO BE SOLVED: To obtain an indicator which is small in the number of parts, is simple in structure and is capable of reducing the electric power consumption by providing a photoconductive member with plural light refraction parts which are disposed apart required spacings at the photoconductive member and radiate incident light to the outside the photoconductive member. SOLUTION: The photoconductive member 1 is constituted by providing one end 2a of a main body 2 with a light incident part 3, disposing the plural light radiating parts 4 apart required intervals up to the other end 2b along the longitudinal direction and disposing the plural light refraction parts 6 within the main body 2. When the light enters the light incident surface 3a, the light is reflected by the main refraction part 5 on the corner side and is guided to the other end 2b side of the main body 2. At this time, the light is reflected by the reflection mirrors of the respective light refraction parts 6 toward the light radiation surfaces 4a of the light radiating parts 4 and the arrival positions at the light refraction parts 6 vary according to the varying intensity of the incident light. When the light emission quantity of a luminous body 7 is regulated, since the plural light radiation surfaces 4a lined up on a straight line radiate light in various forms, the indicator can be used as a level meter indicating a certain quantity.
