Abstract
A semiconductor light-emitting element includes: a growth substrate; a plurality of columnar semiconductor layers on the growth substrate; and an embedded layer with which the plurality of columnar semiconductor layers are covered. Each of the plurality of columnar semiconductor layers includes: an n-type nanowire layer at a center of each of the columnar semiconductor layers; and an active layer on an outer periphery side of the n-type nanowire layer. The embedded layer defines a gap above the growth substrate between adjacent columnar semiconductor layers of the plurality of columnar semiconductor layers.
