PURPOSE:To constitute a titled device so that an energy leak component is emitted without burning at a winding part, and it is not emitted when it is bent, by preparing the winding part which is bent in accordance with a bending direction of the tip part by a smaller curvature than its tip curvature. CONSTITUTION:A tip part 4 of an optical fiber 3 is constituted so that the bending direction is remote-controlled by an irradiating direction control part 5 provided on the outside. Also, in case when the middle part of the optical fiber 3, for instance, the optical fiber is used for the medical purpose, a heat radiating body 6 consisting of a cylindrical body or a columnar body made of a metal having good heat conductivity such as steel, Al, etc. is provided on a part except a part which is inserted into the human body. Said middle part is twisted and wound to this heat radiating body 6 by at least >=1 rotation so that the outside face of its middle part is entirely brought into contact with the heat radiating body 6. |
