PROBLEM TO BE SOLVED: To provide an information transmittal management unit, a mobile communication terminal, an information transmittal confirmation system, and an information transmittal confirmation method where a sender can confirm a transmittal state of information having been sent within an extent at which the privacy of a recipient is not invaded. SOLUTION: When information is sent to a receiver side mobile communication terminal B, an update means 20 updates transmittal status data stored in a 1st storage means 40 from 'un-transmittal' into a 'transmittal state' when confirmation permission data stored in a 2nd storage means 30 indicates 'permission' in response to an update request from a repeater 70. When a transmitter side terminal A makes a confirmation request of the transmittal status data in this state, a transmission means 20 transmits the transmittal status data denoting 'transmittal' to the transmitter terminal A. Furthermore, when the confirmation permission data are set to be 'no permission', even when the recipient receives information, the transmittal status data are not updated into data denoting the transmittal. |
