A light radiation device for use in medical treatment is disclosed. The device comprises a fiber optic cable, a light radiator and a holding pipe. The fiber optic cable transmits therethrough visible light rays and radiates the same from its end surface. The light radiator has a number of densely bundled tapered columns placed opposite the end surface of the fiber optic cable, each column consisting of a plurality of optical conductors. The holding pipe holds the light-radiating end of the fiber optic cable at one end and a light-receiving end of the light radiator at the other end so as to allow the light to pass therethrough and enter into the light radiator. |
