Disclosed is a semiconductor light emitting element (LC) provided with a substrate (110) having one surface on which plural hexagonal-pyramid-shaped protrusions (110b) are provided, a base layer (130) provided so as to be in contact with the surface on which the protrusions (110b) are provided, an n-type semiconductor layer (140) provided so as to be in contact with the base layer (130), a light emitting layer (150) provided so as to be in contact with the n-type semiconductor layer (140), and a p-type semiconductor layer (160) provided so as to be in contact with the light emitting layer (150). Each protrusion (110b) scatters light in lateral and oblique directions within the semiconductor light emitting element (LC). The protrusions are densely arranged on a substrate on which semiconductor layers are laminated, so that the light extraction efficiency is improved.
