A pattern changing sheet (1) is provided with: a number of lenticular lenses (11) which are arranged in a direction orthogonal to an optical axis at a generating line pitch L0, the number corresponding to a single wavelength; and a pattern layer (20) which is disposed on a back side of the lenticular lenses (11) in an opposing manner and which includes a gradation pattern (21)(... dots 21h, 21i, 21j ...) arranged in each generating line pitch L0. The gradation pattern (21) is a pattern including bright portion and dark portion dots in an arrangement direction in the generating line pitch L0. In accordance with the position of a view point, a display pattern in which corresponding dots of each of the lenticular lenses (11) are linked is exhibited, and the display pattern progresses at a predetermined speed ratio with respect to a movement of the view point. The configuration makes it possible to create and provide a pattern changing sheet having a high degree of freedom and adapted for particular uses and the like.
