ABSTRACT:
A light-receiving end structure of an endoscope light guide comprises the illumination light-receiving end plane formed on an illumination light-receiving end portion of the light guide, an adhesive agent applied to the illumination light-receiving end portion to bond together optical fibers constituting the end portion, a transparent heat-resistant disc member mounted on the illumination light-receiving end plane, and a metal support surrounding the light-receiving end portion and the disc member in a liquid-tight state. The heat generated by light beams irradiated on the light-receiving end plane is conducted through the disc member to the support and then released into the open air. Therefore, the light-receiving end portion is not exposed to a high temperature. Accordingly, the light-receiving end structure is prominently increased in effective life.
