PROBLEM TO BE SOLVED: To obtain an antenna device that can be miniaturized without using a slip ring for ensuring electric connection between a fixed part and a movable part about the antenna device having an antenna that is used for satellite communication, etc., and turns in an azimuth direction and in an elevation angle direction. SOLUTION: A rotating member 3 rotates in such a manner a motor 5 rotates to turn the antenna 11 around an azimuthal axis. Meanwhile, a rotating member 7 rotates in such a manner that a motor 9 rotates, and a relative rotation shaft 14 rotates by the relative rotation of the rotating member 3 and the rotating member 7. The rotation of the relative rotation shaft 14 turns the antenna 11 around an elevation angle axis by rotation transmission by a bevel gear 18 and a bevel gear 19.
