A cordless telephone is disclosed that displays the relative position of a communication partner's cordless telephone during conversation between cordless telephones and that includes a received field level detector that measures the received field level; a memory section that inputs and stores the position at which received field level is first detected and positions subsequently detected; a control section that determines the relative position of a communication partner's cordless telephone by performing a three-point measurement based on the results of detecting received field level three times and on the resulting detected positions, and a display section that displays the measurement result.
