Abstract
Provided is a surface light emitting element having a high productivity, a high light emission output and good response characteristics, as well as capable of suppressing an increase of a forward voltage necessary for light emission. A surface light emitting element according to the present invention is a vertical cavity surface light emitting element including: an active layer 5 in which a quantum well layer 51 and a barrier layer 52 are alternately laminated; and reflective layers disposed both above and below the active layer 5, wherein assuming that a center-to-center distance of a plurality of the quantum well layers is L, a light emission wavelength of the surface light emitting element is λ, and an average refractive index of an optical length of a resonator, being a distance between the reflective layers is n, a condition of
