A technique enabling several kinds of contents information to be used in terminals like cellular phones, regardless of the type of terminals without burdening contents providers. A contents conversion server receives, from a terminal, access destination information such as a URL of a contents providing server, and type information on the terminal or on its browser. Next, if the access destination information is interpreted to point to contents information not in the contents conversion server, but in the contents providing server, as an access destination, the contents conversion server obtains the pointed to contents information from the contents providing server. Then, the contents conversion server converts an arbitrary type of obtained contents information, based on the type of information, and moreover, converts the link information, if included, in accordance with a predetermined rule. Consequently, the contents conversion server sends converted contents information to the terminal.
