Abstract:
    A hologram in which authentication information is so recorded as to be difficult to observe in a normal way and to be easy to observe by using color difference when authentication information is ascertained by an authenticator, thereby ensuring a high falsification prevention effect. In the hologram (100) for reproducing a three-directional image, a fine object (11) which is authentication information is disposed behind a blocking object (12) having a size easy to recognize with the naked eye, the authentication information (11) is so recorded as to be not observed in a predetermined direction because the authentication information (11) is blocked by the blocking object (12) and as to be observed in a direction different from the predetermined direction, and the color of the authentication information (11) is different from that of the blocking object (12).
