An illumination device can be configured to be capable of radiating light generated from a light emitting element while efficiently dissipating heat from the light emitting element. The illumination device can also efficiently utilize the light from the light emitting element. The illumination device can include a light emitting element, and a plurality of radially disposed radiation fins for dissipating heat generated by the light emitting element. An aperture for allowing light from the light emitting element to pass therethrough can be formed between adjacent ones of the radiation fins. In addition, a reflection surface for reflecting light which is blocked by the radiation fins when passing through the aperture can be formed on a surface of each of the radiation fins.
