Abstract
Abstract A light rays bathtub comprises a tub (10) having an inner surface (11) formed as a reflection surface and an optical con. ductor (20) for radiating visible light rays into the tub. The bathtub is so constructed that the visible light rays are radiated over the entire area in the tub. An entire body can bath effectively in the light rays consisting of only visible light rays component not containing therin harmful ultraviolet, infrared or the like.
