<P>PROBLEM TO BE SOLVED: To provide a light-emitting device having good light carrying efficiency in the longitudinal direction while achieving linear light emission, achieving reduction in the loss of a light quantity, and being very useful for design involving increase in length. <P>SOLUTION: A rod light carrying guide part 2 and a rod light-emitting guide part 1 are arranged side by side in approximate parallel to adjoin each other along the longitudinal direction. A portion of the light carrying guide part 2 and a portion of the light-emitting guide part 1 are connected to each other along the longitudinal direction without producing an interface therebetween, so that carried light inside the light carrying guide part 2 leaks via the connection portion 7 to the light-emitting guide part 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
