An electronic apparatus with an azimuth meter is capable of measuring an accurate azimuth and is made small even if one or a plurality of magnetized members for generating a magnetic field exists. Magnetic screen is provided for shielding an azimuth sensor from a magnetic field generated from a battery and a stepping motor. Moreover, when the stepping motor rests, an azimuth is measured, and rotor rest time and a direction of the magnetic field generated from a rotor are predicted based on rotor rotation starting time and a direction of a driving current flowing through a coil, and the measured azimuth is corrected according to the predicted result.
