An illusion apparatus for causing an illusion that an object which is not actually moving is perceived to be moving,

• the illusion apparatus comprising a final target object including a final target that is equivalent to an object obtained by superposition of two objects of a target and a dark object which have approximately the same shape or approximately similar shapes or superposition of two objects of a target and a light object which have approximately the same shape or approximately similar shapes, wherein
• the final target object is arranged in a background of which luminance periodically varies over time,
• luminance of the dark object is lower than luminance of the target, luminance of the light object is higher than the luminance of the target, and
• the superposition is an incomplete superposition in which a part of the dark object is hidden by the target or an incomplete superposition in which a part of the light object is hidden by the target.
