A light emitting diode unit comprises a light emitting element D1, a base 1 having a heat dissipating member 12 that dissipates heat generated by the light emitting element D1, and a first lens 2 comprising a reflecting element 214 that reflects light R2 traveling outside of a predetermined angle among the emitted light R emitted by the light emitting element D1 and a refracting element F that refracts light R1 traveling inside of the predetermined angle among the emitted light R each of which is formed integrally, with the first lens 2 mounted integrally on the base 1, and the emitted light R emitted from the light emitting element D1 is made to travel generally toward the same direction by the reflecting element 214 and the refracting element F.
