The communications terminal includes a communications unit to communicate wirelessly with a communications partner terminal. The detection unit detects movement of the communications terminal. The control unit controls the communications terminal so as to vary a communicable area of the communications unit. The communicable area is defined relatively to the communications terminal. The control unit varies the communicable area according to at least magnitude of the movement detected by the detection unit.
