SOLUTION: A mobile terminal device 100a calculates the current position from a radio wave from a GPS satellite 190 and sends it to another mobile terminal device 1090b. The mobile terminal device 100b displays the position information sent from the mobile terminal device 1090a over a map. For the purpose, each mobile terminal device is provided with a map data storage means of storing map data, a map display means of displaying map data managed by the map data storage means, a position detecting means of detecting the current position, a transmitting means of transmitting the position detected by the position detecting means to other mobile terminal devices, a receiving means of receiving positions sent from the other mobile terminal devices, and a position display means of putting a mark on the position received by the receiving means on the map data displayed by the map display means.
