There are provided: a communicating unit (transmitting and receiving unit) that is capable of transmitting and receiving information wirelessly to and from a plurality of electronic cameras and receives identification information peculiar to a device from the electronic cameras; an inputting unit that a user uses to input the identification information peculiar to a device; and a collating unit (information processing unit) for collating the received identification information peculiar to a device with the inputted identification information peculiar to a device. If both pieces of identification information coincide with each other as a result of the collation, the communication device selects a communication device which has transmitted the identification information coinciding with the inputted identification information to transmit information to the communication device thereafter, devices of users wishing to communicate with each other can be easily specified when a plurality of communication devices are connected wirelessly to transmit and receive information. Furthermore, since there are provided an information obtaining unit (wireless interface or the like) for obtaining information owned by a user; a recording unit for recording the information obtained by the information obtaining unit; a first communicating unit (communication line interface) for reading out the information recorded by the recording unit to transmit the information to a destination desired by the user; and a second communicating unit (communication line interface) for transmitting information on a result of the first communicating unit (communication line interface) transmitting the information to a first communication device (portable terminal or the like) on the user side, it becomes possible to notify a user whether or not information that should be transmitted has been surely transmitted.
