A cellular phone 10 transmits a request for management information including size information of object data which is desired to be downloaded, and determines whether a size of the object data exceeds a predetermined value or not, based on the size information. If the size of the object data does not exceed the predetermined value, the cellular phone 10 stores the object data, received in response to the download request, in a temporary storage area. If the size of the object data does exceed the predetermined value, the cellular phone 10 determines whether a free area for storing the object data in a permanent storage area exists or not. If a free area exists, the object data received in response to the download request is stored in the permanent storage area. As a result, the temporary storage area to be used for storing history is not used for storing a large amount of content data, and the history of a number of operations can be held in the temporary storage area without providing a large temporary storage area.
