1. A positioning device comprising:
- a geomagnetism detection section which detects geomagnetism;
an acquisition section which acquires a matching area obtained by checking values of a total magnetic intensity and a magnetic dip of the geomagnetism detected by the geomagnetism detection section against geomagnetic information including values of a total magnetic intensity and a magnetic dip which are associated with an absolute position; and
an identification section which identifies a current location based on the area acquired by the acquisition section.
