ABSTRACT:
It is an important factor in application to the illumination field and the like to obtain a characteristic excellent in power efficiency in a light emitting element. The present invention provides a semiconductor light emitting element including: first and second conductive type semiconductor layers; first and second electrodes respectively provided on the same plane sides as the first and second conductive type semiconductor layers; and a light emitting structure, provided with the second electrode and including the first and second conductive type semiconductor layers, wherein the first electrode provided on an exposed surface of the first conductive type semiconductor layer at least has a translucent first layer and a reflective second layer, and the first layer has projecting portions projected from both sides of the second layer in a cross section of the element crossing over the light emitting structure and the first electrode.
