It is possible to eliminate the problem that a conductive part to a light source is subjected to stress by operation of a needle-pointer, thereby improving reliability. A needle- pointer type meter includes: an indicator plate (1) having a first see- through portion (11) and an indicator portion (12) surrounding the first see-through portion (11); a rotary body (3) having a second see-through portion (31) corresponding to the first see-through portion (11); a drive device (6) for moving the rotary body (3); a needle-pointer (4) mounted on the rotary body (3) and moving along the indicator portion (12) around the first see-through portion (11); light sources (L2) illuminating the needle-pointer (4); and a display device (7) for displaying predetermined information to an observer via the see-through portions (11, 31). A plurality of light sources (L2) are arranged at an interval along the movement route of the needle-pointer (4). The needle-pointer (4) is made of translucent material which emits light when receiving light from a predetermined light source (L2) of the plurality of light sources (L2) while moving.
