A structure (100) for shielding an electronic circuit (220) from radio waves is characterized by that the shield case (300) is formed therein with a cavity which is open in one side (310), that a first electrically conductive layer (330) is formed on an inner surface of the cavity; and that the printed wiring board (200) includes a main board (213) closing the cavity therewith as a cover, an electronic circuit (220) mounted on a lower surface of the main body (213), and a second electrically conductive layer (210) coextensive with the main body and making electrical contact with the first electrically conductive layer (330) when the printed wiring board is put onto the open side (310) of the shield case (300). The second electrically conductive layer cooperates with the first electrically conductive layer to form a shielded space in which an electronic circuit is to be mounted. <IMAGE> <IMAGE> |
