Abstract
According to the present invention, a light diffuser capable of efficiently and uniformly irradiating a wide area of a biological tissue with a light beam such as a laser light beam, which can be readily produced at low cost, and a light-diffusing device comprising the same are provided.Specifically, a coiled light diffuser consisting of a portion for attachment to an optical fiber and a portion for diffusing light transmitted from an optical fiber, which is attached to a light transmission end of an optical fiber for diffusing light transmitted from the optical fiber in a direction differing from the light transmission direction, and which is formed by coiling a wire rod at least the surface of which comprises a light-reflective metal into a cylindrical shape for the irradiation of a biological tissue with a light beam, and a light-diffusing device to which the coiled light diffuser is attached are provided.
