One embodiment of the present invention provides a semiconductor light-emitting element having both high light-extraction efficiency and excellent adhesion between a light-extraction surface and a sealing resin, and it also provides a process for production thereof. This element comprises a semiconductor multilayered film and a light-extraction surface. In the multilayered film, plural semiconductor layers and an active layer are stacked. The light-extraction surface is provided on the multilayered film, and plural micro-projections are formed thereon. These micro-projections have flat top faces parallel to the multilayered film, and they can be formed by an etching process. The etching process is performed by use of a dot pattern as a mask, and the dot pattern is formed by phase separation of a block copolymer.
