The cellular phone 10 makes the data list transmitter 13 transmit a data list of content data stored in the data storage 11, to the cellular phone 20. The cellular phone 20 collates the data list with a check list stored in the check list DB 21 to generate a request list, and transmits the request list to the cellular phone 10. The cellular phone 10 extracts the content data recorded in the received request list from the data storage 11 and transmits the content data to the cellular phone 20. The cellular phone 20 receives the content data through the data receiver 26.
