This autonomous working machine, which works while autonomously traveling in a working area, includes: a plurality of magnetic field detection sensors which detect a magnetic field generated when applying a current to a station wire that induces the autonomous working machine toward a charging station for feeding power; and a specifying unit which specifies the angle of the autonomous working machine with respect to the charging station on the basis of comparison between detection results of the magnetic field detection sensors, when the autonomous working machine moves from a charging position of the charging station to the working area, or when the autonomous working machine moves from the working area to the charging position.
