摘要：PROBLEM TO BE SOLVED: To easily provide a mixed color light emitting element which is manufactured in the same process as for a conventional monochromatic light emitting element at a cost lower than for a light emitting element manufactured on a GaN substrate containing fluorescence core. SOLUTION: Nitride compound semiconductor layers 2-6 are laminated on a substrate 1 comprising an Al2O3 single crystal in which Ti is doped, or an Al2O3-contained material in which Ti is doped, constituting a light-emitting element.
