摘要

PPROBLEM TO BE SOLVED: To provide a forgery prevention laminated body which is inexpensive, high in productivity, high in visibility, has a visual effect excellent in decorativeness as well and comprises an optical element in which a relief structure and a relief-effect layer are highly accurately arranged, a forgery prevention transfer foil, a forgery prevention seal, a forgery prevention medium and a manufacturing method of them. PSOLUTION: The forgery prevention laminated body is configured to successively stack at least a relief structure forming layer 2, a relief structure portion 3 which is partially provided on one side of the relief structure forming layer 2, a fine bump structure portion 4 which is partially provided on the same surface, so as not to overlap with the relief structure portion 3 and has water repellency, and the relief-effect layer 5 which comprises an optical thin film arranged so as to cover only the part except the fine bump structure portion 4 and reflects at least a part of light after transmitting the relief structure forming layer 2.
