Abstract

A light-emitting element array includes a substrate, plural light-emitting elements arranged on the substrate, plural constriction grooves being provided in a periphery of each of the plural light-emitting elements, and forming a current constriction layer that constricts a current flowing through a light-emitting layer by oxidizing the light-emitting layer, and a block separation portion that is formed so as to overlap a part of the plural constriction grooves in plan view, and separates the plural light-emitting elements into plural blocks.
