A portable communication device including a GPS antenna, a GPS processing circuit for determining a location of the device based on a signal received by the antenna, a location information processing circuit for detecting the location information corresponding to a determined result, a key input device for inputting a telephone number of a communication terminal device for transmitting the location information, a control circuit, and a transmitting circuit. The key input device is provided with a LOST key. The control circuit feeds the location information detected by the location information processing circuit to the transmitting circuit when the LOST key is manipulated. The transmitting circuit transmits the location information to the communication terminal device having the inputted telephone number. This realizes a portable communication device which is adapted to notify others of the accurate present location of the device.
