    • An objective of the present invention is to provide a substrate that can achieve high light extraction efficiency, and to provide an organic EL light-emitting apparatus with high light-emitting efficiency by using such a substrate. The present invention is a substrate (1) comprising a transparent substrate (10) and a light-concentrating structural body layer (30), wherein the light-concentrating structural body layer (30) includes a plurality of structural bodies (25) having a conic shape or a hemispherical shape, with the bottom faces of the plurality of structural bodies (25) having a conic shape or a hemispherical shape being located on the same plane. The structural body (25) is preferably a structural body having a cone shape, a square pyramid shape or a triangular pyramid shape.
