Summary:PROBLEM TO BE SOLVED: To provide a method for presenting a stereogram by which images for a left eye and a right eye are superimposed and displayed within the same visual field without using a special tool such as stereoscopic vision spectacles and can be observed in an easy and natural convergence state by naked eyes in the case of binocular stereoscopic vision. SOLUTION: A structural part 310 having a surface in bellows shape is formed by combining wedged surfaces, and the image for the right eye 314 is presented on a surface (R) positioned on the right side of the ridge line of the apex part of a wedge and the image for the left eye 312 is presented on a surface (L) positioned on the left side from the ridge line. The structural part 310 is constituted so that the visual field of the left eye is covered with the wedged surface seen only from the left eye and the visual field of the right eye is covered with the wedged surface seen only from the right eye when it is seen from a specified place by a person. Therefore, only the image 312 is viewed by the left eye 152 and only the image 314 is viewed by the right eye 154 from the specified place, so that a stereoscopic picture is viewed.
