The image three-dimensional recognition apparatus is an apparatus for making it possible for an observer to recognize a planar image as a three-dimensional image, and has a first mirror, a second mirror and a mirror fixing part. The mirrors have the mirror planes, respectively. The mirror fixing part fixes the mirrors, and has a base and two support members arranged on the base. The mirrors are fixed at a position sandwiched between the support members by attaching the side faces of the mirrors to the support members. The first mirror is located directly below the second mirror. The mirror plane of the second mirror is directed toward the planar image displayed in a screen of a display device, and is inclined obliquely downward. The mirror plane of the first mirror is directed toward the observer and is inclined obliquely upward.
