<P>PROBLEM TO BE SOLVED: To provide a transfer foil which is not destroyed even on a fibrous base material having stretching properties such as a cloth, and a hologram medium using the same. <P>SOLUTION: In a hologram medium, a hologram layer is provided on a base material configured by periodically arranging yarn, which is made of a single fiber or made by twisting a plurality of fibers. The hologram layer includes a diffraction structure and a metallic reflective layer formed on the diffraction structure, and is periodically arranged so as to be parallel to an extending direction of the yarn. A periodic pitch of the yarn is coincident with a periodic pitch of the metallic reflective layer in a direction parallel to at least one of warp yarn and weft yarn. <P>COPYRIGHT: (C)2012,JPO&INPIT |
