ABSTRACT:
A gyrocompass has a gyrosphere which incorporates a rotor and floats in a liquid tank filled with an electrolyte, and a plurality of electrodes which are disposed in the gyrosphere and the liquid tank, and are respectively opposed through the electrolyte, wherein at least one circuit which supplies electric power to the rotor involves the electrodes, and the plurality of the electrodes includes a first belt-shaped electrode disposed in an equatorial portion of the gyrosphere, the first belt-shaped electrode is formed of a metal which is corrosion-resistant and is a good conductor, and an insulating film is formed on a portion of a surface of the first belt-shaped electrode.
