PURPOSE: To provide an image reproducing device which is made smaller in size, lighter in weight and is advantageous in carrying and storing compared with reproduction of edgelitho-hologram using a conventional light guiding block. CONSTITUTION: A rear surface side 7b of an optical member 7, of which a surface side 7a is made to have ruggedness of a step shape is stuck to a holographic stereogram 6 and illumination light 9 is made incident from the surface side 7a with a prescribed angle, for example 60°. The optical member 7 is formed of optical glass or a transparent plastic or the like, for example, and a plurality of light incident surfaces 8 to which the illumination light 9 is made vertically incident are formed at the surface side 7a. The optical member 7 makes an incident angleθof the illumination light 9 to a boundary 22 between the holographic stereogram 6 and itself an angle with which surface reflection at the boundary 22 can be suppressed, for example 60°.
