Abstract:
1. A semiconductor light-emitting element comprising a semiconductor layer comprising an n-type semiconductor layer, an active layer and a p-type semiconductor layer, and a metal electrode layer which is provided on said semiconductor layer; wherein said metal electrode layer comprises: a metal part so continuous that any pair of point-positions in said metal part is continuously connected without breaks, and plural openings which penetrate through said metal electrode layer and which have an average opening diameter of 10 nm to ⅓ of a wavelength of light emitted from said active layer, said openings being positioned in a whole area of said metal electrode layer, and said openings being positioned at random in said metal electrode layer, under the condition that said metal part in 90% or more of the whole area of said metal electrode layer continues linearly without breaks by said openings in a straight distance of not more than ⅓ of said wavelength of light.
