摘要： PROBLEM TO BE SOLVED: To make it possible to easily identify kinds of hologram elements with the naked eye and to manufacture a variety of hologram elements at a low cost. SOLUTION: This hologram element 10 has colored members 4 for element identification at the outside of a hologram pattern 3 which is a diffraction pattern disposed on one surface of a substrate 1. The kind of this hologram element 10 can be identified only by the color of the colored members 4 with the naked eye and it is not necessary to magnify a kind identifying mark through a microscope unlike a conventional hologram element. Since the colored members 4 are disposed in grooves in cutting marks 5 at the outside of the hologram pattern 3, the element can be divided in a good state with no rise of the colored members in a dicing step. The grooves can be formed in a photolithographic step and an etching step of forming the hologram pattern 3. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent a crack from occurring in a hologram element by reducing the swelling distortion of a substrate.
SOLUTION: The hologram element includes a substrate on which a hologram diffraction grating is formed, and a low moisture permeable membrane covering the hologram diffraction grating, and has an exposed area which is not covered with the low moisture permeable membrane. Generally, an occurrence percentage of cracks is influenced by the swelling distortion caused by the hygroscopic property of the substrate. Since the hologram element of this invention has an exposed area which is not covered with the low moisture permeable membrane on the substrate, the element can absorb moisture also from the surface with the low moisture permeable membrane formed thereon, therefore, the swelling distortion is relaxed and the cracks are prevented from occurring.
