To provide a means which enables even not a skilled worker to easily and surely stick films of three primary colors to a filter wheel used for a color sepn. type color camera in the work of sticking the films.

The three films 3 are successively placed to meet the partition plates 10 arranged on the top face of a base plate 6B and, thereafter, the filter wheel 1 with its film-sticking surface downward is placed on the base plate 6B. On the base plate 6A, supporting columns 7 are erected at its respective corner parts and the base plate 6B is moved vertically along these supporting columns 7 by the elastic force of the springs disposed around the supporting columns 7. Even if push pins 12 erected on the base plate 6A after the placement of the filter wheel 1 lower the base plate 6B, the films 3 are prevented from lowering and, therefore, the removal of the filter wheel simultaneously with the sticking of the film is simultaneously executable with this jig.
