<p>Disclosed is a mobile wireless device which can execute a plurality of wireless applications despite being small and thin. A second power supply section (9) supplies power to an external conductor (53) of a first coaxial cable (5) by using the external conductor (53) of the first coaxial cable (5) which electrically connects a first power supply section (4) and a first antenna element (7). The external conductor (53) is used as a monopole antenna corresponding to the second power supply section (9), by connecting one end of the external conductor (53) to a ground pattern of a first circuit board (2) by way of a first reactance element (12) and connecting the other end of the external conductor (53) to the ground pattern of the first circuit board (2) by way of a second reactance element (13). It is therefore possible to execute two wireless applications without increasing the number of antennas.</p>
