To provide a means for notifying an own safety state to own family when a disaster sufferer caused by big earthquake etc. moves toward one's home, and for confirming safety of the other family member.

Contact address telephone number for identifying a family member of an owner of a cellular phone 102A, owner's name, and status information relating to a status such as injury of the owner can be transmitted until a predetermined transmission distance from the cellular phone 102A which performs as a ZigBee terminal. A ZigBee base station 142 which receives these pieces of information transmits safety information added with location, date, and time to a financial institution network 140 configured by a private line. A message board server 230 which receives the safety information via a gateway 190 stores the received safety information by correlating with every family, while retransmits the safety information of the other family member to the cellular phone 102A in response to requests.
