SCANNING ENDOSCOPE AND SCANNING ENDOSCOPE MANUFACTURING METHOD

摘要

A scanning endoscope 2 includes an optical fiber 14 that guides a light with which a living body is illuminated, a holding member 41 having an insertion hole 41h through which the optical fiber 14 is inserted, in which the optical fiber 14 is provided so as to extend from a distal end by a predetermined length and a concave portion 41g that communicates with the insertion hole 41h is formed on the distal end, a drive portion 15 that is provided in the holding member 41, and causes a free end of the optical fiber 14 that extends from the distal end of the holding member 41 to scan, and an adhesive portion 46 that is coated on or filled in the concave portion 4 1 g to firmly fix the optical fiber 14 and the holding member 41 to each other, and has a plane which is flush with the distal end of the holding member 41 formed thereon, whereby a variation in length of the free end of the optical fiber in each of respective individual pieces at a production time is eliminated, and a scanning characteristic of the optical fiber becomes constant in each of the respective individual pieces.
