To provide a surface light emitting element capable of maintaining characteristics of the surface light emitting element and accurately detecting emitted light. A surface light emitting element includes a light emitting element part, provided on a semiconductor substrate and emitting light perpendicular to the semiconductor substrate; a light detecting part, provided on the light emitting element part; a first electrode and a second electrode, which drives the light detecting part. The light detecting part includes a second contact layer; a light absorption layer, provided on the second contact layer; and a first contact layer provided on the light absorption layer. The first contact layer includes a first light passage part; and at least one electrode coupling part, extending from the first light passage part. The first electrode is provided on the first electrode coupling part of the first contact layer.
