PROBLEM TO BE SOLVED: To provide a stereoscopic printed matter for achieving a proper stereoscopic view even in the case of seeing from a bird's eye view point. SOLUTION: The stereoscopic printed matter printing a stereoscopic image includes a stereoscopic optical device (lenticular lens) for guiding light at a different place by separating image light of a left eye image of the stereoscopic image from image light of a right eye image. The stereoscopic optical device is a device matching a focus at the time when seeing from a view point VP overlooking a printed face with the display screen in both of a foreground side region and an interior region of the printed face. The stereoscopic optical device uses a lens in which a thickness in the interior region of the printed face is thinner than that of the foreground region, and a lens in which the radius of curvature in the interior region is larger than that of the foreground region. Otherwise, the stereoscopic optical device uses a lens in which a cross sectional shape at the time when being cut with a face including right and left visual direction from the bird's eye point of view has the same cross sectional shape as those of the interior region and the foreground region.
