<P>PROBLEM TO BE SOLVED: To provide a light-emitting unit capable of irradiating light beams from a wide surface of a light guide body with luminance unevenness restrained at each irradiation position. <P>SOLUTION: The light-emitting unit 2A is structured of a light-emitting element 3, and a light guide body 4 made of a transparent material. The light guide body 4 is of a plate shape bent in an arc shape, provided with a light-incident face 421 for letting in light beams C emitted from the light-emitting element 3 formed at one end face of the plate shape, and at the same time, provided with a light-irradiating face 411 for irradiating the light beams C bent inside the light guide body 4 toward outside of the light guide body 4, formed at one of the surfaces of the plate shape. <P>COPYRIGHT: (C)2008,JPO&INPIT |
