ABSTRACT:
A portable radio communication apparatus includes a printed circuit board, an antenna section and a radio section installed on the board, a housing, and a connector. The radio section includes electronic parts of which connecting terminals are connected to the printed circuit board and of which conductor sections formed on outer surface thereof are connected to the grounding section. The housing accommodates therein the printed circuit board, the antenna section, and the radio section. The housing has a conductor film formed on an inner surface thereof. The conductor sections of the electronic parts are connected to the conductor film on the inner surface of the housing via the connector. Since the shielding case and the connector conventionally used are unnecessary, the size and weight of the apparatus can be reduced.
