PROBLEM TO BE SOLVED: To provide an optical decoration device in which the extreme unevenness of light is hard to be generated, and which enables further complicated optical decoration.SOLUTION: An optical decoration device 1 is equipped with an inner lens 20 which has optical transparency, and an outer lens 20 which has optical transparency and is disposed on the outside of the inner lens 20 at a predetermined interval. The optical decoration device 1 has a rotor 3 configured so as to rotate about a predetermined rotation axis A1, a drive source 7 for rotating the rotor 3 about the rotation axis A1, a diffusion sheet 5 disposed separately from the rotor 3 on the outside in a rotation radial direction of the rotor 3, a first light source portion 11 for emitting light toward the inner lens 20, and a second light source portion 12 for emitting light toward the outer lens 30. |
