摘要： The present invention provides a semiconductor light-emitting element comprising an electrode part excellent in ohmic contact and capable of emitting light from the whole surface. An electrode layer placed on the light-extraction side comprises a metal part and plural openings. The metal part is so continuous that any pair of point-positions in the part is continuously connected without breaks, and the metal part in 95% or more of the whole area continues linearly without breaks by the openings in a straight distance of not more than ⅓ of the wavelength of light emitted from an active layer. The average opening diameter is of 10 nm to ⅓ of the wavelength of emitted light. The electrode layer has a thickness of 10 nm to 200 nm, and is in good ohmic contact with a semiconductor layer.
