Summary:PROBLEM TO BE SOLVED: To provide an authenticity determination device employing a hologram that improves security more than before.SOLUTION: A first enclosure 61 and a second enclosure 62 are openably and closably supported via a hinge. An image pickup element 5 is arranged in the first enclosure 61, and a first hologram 2, a second hologram 3, and a light source 4 are arranged in the second enclosure 62. When the first enclosure 61 and the second enclosure 62 are closed, interference light in which data on the first hologram interferes with data on the second hologram is generated by an irradiation of light from the light source 4. The interference light is acquired by the image pickup element 5, and an authenticity determination of the second hologram is performed.
