<P>PROBLEM TO BE SOLVED: To provide a fine rod shaped light emitting element which enables easy electrode connection with a simple structure and achieves high luminous efficiency. <P>SOLUTION: A rod shaped structure light emitting element includes: a semiconductor core 11 formed by a rod shaped n type GaN having a circular cross section; and a semiconductor layer 12 formed by a p type GaN so as to cover a part of the semiconductor core 11. A part of an outer peripheral surface of the semiconductor core 11 is exposed. One electrode is connected with an exposed portion 11a and an electrode is connected with the semiconductor layer 12 on the other end side of the semiconductor core 11. The structure allows the electrodes to be connected with both ends thereof in a separate manner and thereby preventing short circuits. <P>COPYRIGHT: (C)2013,JPO&INPIT |
