PROBLEM TO BE SOLVED: To provide a lighting device provided with a rod-like light guide body and improving lighting effect.SOLUTION: The lighting device includes: a rectangular body 5 having a mounting surface 3 and an emission surface 4; a rectangular light guide body 6 installed inside the body 5; and a light source 8 making the light from an incident surface 7 of the light guide body 6 incident into the light guide body 6. The light guide body 6 is structured that a surface facing the emission surface 4 of the body 5 corresponds to the emission part 11, and a surface of the emission part 11 which is opposite to the emission surface 4 of the body 5 corresponds to a reflection part 12. At the emission part 11 of the light guide body 6, a mounting surface reflection part 13 branched from the reflection part 12 is mounted on a side opposite to the mounting surface 3 of the body 5. The mounting surface reflection part 13 is made project to a side opposite to the emission part 11 from the branch part from the reflection part 12. |
