Abstract

PURPOSE:To clearly observe the rugged shapes of a part to be observed, by providing plural light guides whose lighting directions are different respectively. CONSTITUTION:An insertion tip part of an endoscope is constituted of an image guide 7 and the second light guide 9 inserted into the center part of the first cylindrical light guide 8. The tip of the image guide 7 is opposed to an image formation optical system 12 consisting of plural lenses 11, and its rear end is opposed to the eyepiece part. On the tips of the light guides 8, 9, a conical wedge 15 having a small hole 14 is provided, by which the tip of the light guide 8 is bent in the diameter direction. A part to be observed (a) is illuminated from different directions by illumination light beams L1, L2 emitted from the light guides 8, 9. In this regard, the rear ends of the light guides are connected to a light source which is capable of controlling the quantity of light.
