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.

Abstract: An illumination apparatus includes a light source and a light guide formed in a rod shape. An end surface in a longitudinal direction is an incident surface that receives light emitted from the light source. Diffusing patterns are formed on the light guide, and intervals between the diffusing patterns closer to the incident surface in a first area close to the incident surface are smaller than intervals between the diffusing patterns closer to the incident surface in a second area farther from the incident surface than the first area.
