The film holder has a stem portion, an engagement portion formed at one end of the stem portion a film-mounting portion composed of two support portions formed at the other end of the stem portion and extending out in an opposing relationship from the stem portion. Plural film-mounting projections are provided at different levels in the direction of the thickness of the film holder in the proximity of each of free end portions and base portions of the respective support portions, whereby a film can be placed between the support portions while being held between the projections.
