Provided is an artificial nail that has electronic paper as a display body, has a simple configuration, and easily updates display. An artificial nail 1 having electronic paper as a display body is mounted on a user's nail using a fixing member 2 such as a conductive adhesive. In a state where the artificial nail 1 is mounted, an ion wind is generated by the display updating device 3 and the generated ion wind is blown onto the artificial nail 1. By the charging by the ion wind, a potential is applied to the electronic paper included in the artificial nail 1, and the display of the electronic paper is updated to a color corresponding to the potential.
