Abstract
A first GaN group light emitting element that emits blue light, a second GaN group light emitting element that emits green light, and a third light emitting element that emits red light are provided on a first lead terminal, a second lead terminal, and a third lead terminal, respectively. These lead terminals are secured by a securing member. A second portion in the first lead terminal and a second portion in the second lead terminal are wider than a second portion in the third lead electrode. The second portion of the third lead terminal is wider than parts corresponding to second portions of the fourth lead terminal to the sixth lead terminal.
