A position measurement device comprising: positional data acquisition means configured to measure a present position to acquire positional data; positional data storage means configured to sequentially store the positional data acquired by the positional data acquisition means; determination means configured to determine, on the basis of the positional data sequentially stored by the positional data storage means and a predetermined criterion, whether a position of a user at a present time is a position of a location to be recorded; and locational information storage means configured to store, if the determination means determines that the position of the user at the present time is the position of the location to be recorded, the positional data of the position as locational information, wherein the determination means is configured to determine, on the basis of the positional data sequentially stored by the positional data storage means and the predetermined criterion, whether a user stays within a predetermined size of area for over a predetermined time, and to determine, if determined that the user stays within the predetermined size of area, that the position of the user at the present time is the position of the location to be recorded, wherein the determination means is further configured to determine whether a user stays for over a predetermined time in each of a plurality of areas, the position measurement device being characterized in that each of the plurality of areas has a different size (R1, R2, R3), the determinations being performed using each of a plurality of different predetermined times (T1, T2, T3) corresponding to each of the plurality of areas. positional data acquisition means configured to measure a present position to acquire positional data; positional data storage means configured to sequentially store the positional data acquired by the positional data acquisition means; determination means configured to determine, on the basis of the positional data sequentially stored by the positional data storage means and a predetermined criterion, whether a position of a user at a present time is a position of a location to be recorded; and locational information storage means configured to store, if the determination means determines that the position of the user at the present time is the position of the location to be recorded, the positional data of the position as locational information, wherein the determination means is configured to determine, on the basis of the positional data sequentially stored by the positional data storage means and the predetermined criterion, whether a user stays within a predetermined size of area for over a predetermined time, and to determine, if determined that the user stays within the predetermined size of area, that the position of the user at the present time is the position of the location to be recorded, wherein the determination means is further configured to determine whether a user stays for over a predetermined time in each of a plurality of areas, the position measurement device being characterized in that each of the plurality of areas has a different size (R1, R2, R3), the determinations being performed using each of a plurality of different predetermined times (T1, T2, T3) corresponding to each of the plurality of areas.
