| 1. A folding portable wireless unit including an upper case and a lower case connected via a hinge section so that the upper
case and the lower case can be opened or closed, comprising:
an upper case antenna element provided in the upper case;
a feedpoint section for feeding with power from a circuit board provided in the lower case to the upper case antenna element;
and
a conductor element having an electrical length resonant with an operating frequency, one end of the conductor element being
electrically connected to a ground pattern of the circuit board and the other end of the conductor element being open;
wherein
the hinge section is formed of conductive metal,
the upper case antenna element is fed with power from the circuit board via the feed point section provided on one side end
of the hinge section, and
the other side end of the hinge section is electrically connected with the ground pattern of the circuit board via a reactance
element set to have a predetermined value.
