1. A magnetic azimuth measurement apparatus comprising:

  • magnetic detection means having two or more magnetic detection devices with directionality, the magnetic detection devices being disposed at equal intervals based on a predetermined rule in such a way that directionalities thereof are different from each another;

    sampling means for sequentially switching and sampling electromagnetic conversion outputs of magnetic detection devices of the magnetic detection means;

    condition determining means for determining whether or not the electromagnetic conversion output being sequentially switched and sampled by the sampling means meets a predetermined condition; and

    azimuth information output means for outputting magnetic azimuth information based on a result of the determination of the condition determining means.
