<P>PROBLEM TO BE SOLVED: To provide an endoscope which is easily inserted into a biological tubule such as a blood vessel by detecting the position of a distal end with X-rays without thickening an insertion part. <P>SOLUTION: The mutually contacting peripheral side parts of a skin tube 35, a light guide 31, an image guide 32 and an object optical member 33 of the insertion part 30 of the endoscope 10 are fixed with an adhesive 36 at the distal end part 30E of the insertion part. The adhesive 36 contains fine particle powder 36b consisting of an X ray opaque material such as Pt, Au. Furthermore, a gap between the respective optical fibers 31a of the light guide 31 is also filled with the adhesive 36. Thus, X ray opaque property spreads to not only the boundaries between the respective members 31, 32, 33 and 35 but also to the inside of the light guide. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
