Abstract

PROBLEM TO BE SOLVED: To make it possible to irradiate the specific point of a lesion, etc., positioned on the side of an optical chip on which a reflection surface for totally reflecting incident light in a specified direction in formed, with a laser beam, by providing a device irradiating with laser beam with the optical chip descried above. SOLUTION: An insertion part 1 is inserted into the body and a front end member 7 is disposed to face a lesion. The colored part 15 of a sleeve 16 is then observed and the direction of the colored part 15 is visually checked. Whether the laser beam emitted from the optical chip 14 is made incident on the lesion or not is thereby decided. If the direction of the colored part 15 is in the state of not making the laser beam emitted from the optical chip 14 incident on the lesion, a rotating position adjusting member 24 existing on the outside of the insertion part 1 of an optical fiber 13 is properly turned by the fingertips, by which the sleeve 16 is turned together with the optical fiber 13. The direction of the colored part 15 is adjusted to the position where the laser beam from the optical chip 14 is made incident on the lesion. The laser beam is reflected by the reflection surface 19 and is diffused by the recessed surface 20 so as to be cast to the lesion.
