Claim Text:
1. A semiconductor light-emitting element comprising: a double-mesa structure of semiconductor formed to have a cylindrical cross section, the double-mesa structure including an upper mesa structure and a lower mesa structure, the upper mesa structure being stacked on top of the lower mesa structure such that a portion of a lower reflecting mirror film at the top of the lower mesa structure is not covered by the upper mesa structure; an insulating member formed to fill a space surrounding the double-mesa structure, with the insulating member comprising a lower insulating member and an upper insulting member covering the lower insulating member; and a first electrode formed on the upper insulating member to come into contact with part of a top surface of the double-mesa structure; wherein the lower insulating member has multiple lower air pillars in the form of a matrix that are formed in an area in the lower insulating member directly underneath the first electrode and in an area in the lower insulating member not directly underneath the first electrode in a layout view, and the upper insulating member has multiple upper air pillars in areas surrounding the first electrode, without having any air pillar in areas of the upper insulating member that are directly underneath the first electrode in the layout view.
