摘要 A light emitting apparatus can prevent unevenness in illuminance from being produced. This light emitting apparatus 5 has: light emitting elements 3 that emit light; and light flux controlling members 4 that control the traveling directions of light emitted from light emitting elements 3, and a plurality of grid convex parts 13 are formed in back surface 12 (i.e. lens bottom surface) of light flux controlling member 4. Grid convex parts 13 vary the incident angles of light incident on back surface 12 of light flux controlling member 4. Therefore, light incident from back surface 12 is scattered without being concentrated, and is emitted from light flux controlling member 4.
