In a portable radio device in which both an antenna for cell phone and an antenna for receiving GPS data are installed, an object of the present invention is to decrease influence of the antennas on one another with respect to deterioration of their radio performances. According to the present invention, in a portable radio device in which an operating part housing (11) and a display part housing (12) are connected by way of a hinge part (13) in a freely foldable manner to conduct both telephone conversation and reception of GPS data, an antenna (20) for the telephone conversation is provided at one side of the operating part housing (11) in a lateral direction, and at the same time, an antenna (21) for receiving the GPS data is mounted to a base board (22) in the display part housing (12) in its end area at an opposite side to the hinge part (13). With this arrangement, both the antennas (20), (21) can be spaced from each other, and deterioration of their radio performances can be restrained.
