Abstract
A light emitting element array includes plural semiconductor stacked structures each including a light emitting unit that is formed on a substrate, and a light amplification unit that extends from the light emitting unit along a substrate surface of the substrate to have a length in an extension direction which is longer than that of the light emitting unit, amplifies light propagating in the extension direction from the light emitting unit, and emits the amplified light from a light emission portion formed along the extension direction, wherein the plural semiconductor stacked structures are arranged such that the extension directions of the respective light amplification units are substantially parallel to each other.
