5. An information browsing system including an information delivery server that delivers information, a mobile terminal that displays off-line data and a relay server that relays the information delivered from the information delivery server as off-line data to the mobile terminal connected to each other in a data communicable manner, comprising:

an update frequency discriminating unit to determine an update frequency of the information for each of the mobile terminals based on display situation data of the information received from the mobile terminal;

an off-line data creating unit to determine whether to create off-line data to be transmitted to the mobile terminal for each of the mobile terminals based on an update frequency of the determined information and creating off-line data to be transmitted to the mobile terminal from the information delivered from the information delivery server when said determining indicates that the off-line data is to be created; and

an off-line data transferring unit to transfer an update date and time of the information and update frequency of the information as well as the created off-line data to the mobile terminal, and

the mobile terminal configured to execute an operation including;

recording display situation data per region of the off-line data displayed;

storing off-line data previously received from the relay server;

acquiring, upon receiving a request to display the off-line data stored, an update date and time, and update frequency of the off-line data and determining whether necessary to update the off-line data stored based on the update date and time, and update frequency;

acquiring, when determining that the off-line data stored needs to be updated, display situation data recorded and transmitting the display situation data to the relay server;

receiving the off-line data created by the relay server based on the display situation data, update date and time, and update frequency of the off-line data from the relay server and updating off-line data previously received from the relay server and stored in the off-line data to off-line data newly received from the relay server;

displaying off-line data previously received from the relay server and stored when determining that the off-line data stored need not be updated and displaying off-line data newly received from the relay server and stored when determining that the off-line data stored needs to be updated, and
