description Disclosed is a portable wireless terminal wherein deterioration in antenna performance when placed on a metal desk or other structure can be prevented without sacrificing designability and without increasing the number of components. In this terminal, a hinge part (103) functions as an antenna which resonates at a frequency of a first wireless system (150). A whip antenna (112) faces the surface of a first circuit board (104) that is opposite the surface faced by an input device (115), is disposed substantially parallel to the first circuit board (104), and resonates at a frequency of a second wireless system (160). A second contact spring (110) electrically connects a second wireless circuit (108) to the antenna element of a whip antenna (112) and is disposed perpendicularly to the first circuit board (104). A switch (113) grounds the whip antenna (112) and second contact spring (110) to the first circuit board (104) when the second wireless system (160) is not operating.
