PROBLEM TO BE SOLVED: To provide an antenna device that is a magnetic coupling type and its communication distance is long.SOLUTION: An antenna device 10 is a magnetic coupling type antenna device, and includes: a metal plate 130; a tabular magnetic body 110 that is placed at one surface side of the metal plate; and a coiled antenna that is wound around the magnetic body 110. The antenna device communicates by magnetically coupling with magnetic flux generated by a communication opposite party antenna device. The magnetic body 110 is rectangular parallelepiped sinter ferrite. |
