<p>PROBLEM TO BE SOLVED: To suppress the fluctuations of the potential of the ground for a printed circuit board, or a radiation noise due to a standing wave or the like generated due to the electric connection of the ground of the printed wiring board with a conductive member, constituting a case body in an electronic equipment in which a printed circuit board is arranged inside the case body. SOLUTION: A case body 1 constituted of a conductive member is provided with housing parts 21a and 21b, and a print circuit board 2a is arranged in the housing part 21a. A ground is formed on the print circuit board 2a, and the ground is connected electrically via a connecting part 3a with the case body 1. A metallic board 4 whose maximum area surface faces opposite to one face of the print circuit board 2a in the neighborhood of the print circuit board 2a is arranged in the housing part 21a. A supporting member 6 constituted of a conductive member is formed in the neighboring part of the metallic board 4 of the case body 1, and the supporting member 6 and the metallic board 4 is electrically connected via a lead type electronic component 5 which has a prescribed impedance.</p> |
