PROBLEM TO BE SOLVED: To provide a semiconductor light emitting element having high performance in a high efficiency with high reliability by providing a constitution capable of producing in a mass production, by using a material considering its environment and controlling a light emitting wavelength in from green to ultraviolet wavelength regions. SOLUTION: A hexagonal crystal ZnO has a large exciton bonding energy, and hence exciton of high density exists even at ambient temperature. Thus, when the ZnO is used for an active layer 101, the element having a high light emitting efficiency is obtained. When a substrate (104) made of a hexagonal group III-V compound is used, a lattice alignment can be easily achieved. Accordingly, good epitaxial growth film of the hexagonal ZnO is obtained, and the efficient semiconductor light emitting element can be obtained.
