A pedestrian navigation device ( 10 A) of this invention comprises a position information reception portion ( 12 ), which obtains current position information from a GPS ( 20 ); a position information analysis portion ( 13 ), which analyzes current position information received by the position information reception portion ( 12 ) and calculates the current position; a MAPDB (Map Data Base) ( 14 ), which stores map information; a central processing portion ( 11 ), which calculates current position display information, based on the current position calculated by the position information analysis portion ( 13 ) and on map information stored in the MAPDB ( 14 ); a display portion, which displays current position display information calculated by the central processing portion ( 11 ); and an input portion ( 16 ), which inputs route search conditions and issues instructions to begin navigation. By this means, a pedestrian navigation device is provided which, when navigating a pedestrian route, is able to accurately detect the direction of advance through judgment of stops and suppression of meandering.
