1. A stereoscopic image forming device to be formed in a ring shape or a shape partly using a ring shape when viewed from above, the stereoscopic image forming device configured to form in the air a stereoscopic image of an object by reflecting a light L from the object once off a first vertical light reflective member and once off a second vertical light reflective member while the light L passes through the stereoscopic image forming device, comprising:
a plurality of first vertical light reflective members provided in one side of a transparent flat plate material, the first vertical light reflective members each formed along a radius of a circle centered on a reference point X, the first vertical light reflective members arranged radially around the reference point X; and
a plurality of second vertical light reflective members provided in the other side of the transparent flat plate material, the second vertical light reflective members each curved along each of a plurality of concentric circles centered on a reference point Y overlapping on the reference point X when viewed from above, the second vertical light reflective members intersecting with the first vertical light reflective members when viewed from above.
