Abstract:
There is provided with an illumination device. The illumination device has a circuit board; a light source movable relative to the circuit board; a rod-like light guide that is configured to guide light from the light source and that is elongated in a longitudinal direction; and a flexible wiring configured to supply electricity from the circuit board to the light source. The light source is capable of moving in the longitudinal direction to reduce fluctuation in distance between the light source and a light receiving surface of the light guide when an end portion of the light guide in the longitudinal direction moves in the longitudinal direction.
