description PROBLEM TO BE SOLVED: To provide a fixing method, by which the degradation of transmission characteristics of an optical element in a wavelength region being the utilization purpose of the optical element at the time of performing the fixing of optical elements, such as objective lens made of plastic that utilizes ultraviolet-curing adhesives. SOLUTION: In this fixing method of the optical element, a compound objective lens 20 is arranged at a position facing the exiting end of a lightguide member 55 in the state that it is placed on a bobbin 40 and a fixing part 31 is irradiated with ultraviolet-curing light, supplied to the proper place between the compound objective lens 20 and a lens support part 41 and the fixing part 31 is cured in a short time.
