Claim:
1. A reinforcing member for a printed wiring board, which is disposed opposite to a predetermined part of a ground wiring pattern of the printed wiring board, the reinforcing member comprising: a conductive metal base; a first surface layer formed on a first side of the conductive metal base and opposing and in electrical conduction with the predetermined part of the ground wiring pattern via a conductive composition layer; a second surface layer formed on a second side of the conductive metal base and in electrical conduction with an external ground member which is at a ground potential, wherein, the first side and the second side are on opposite sides of the conductive metal base, the second surface layer has higher conductivity and corrosion resistance than the metal base, and the second surface layer is 0.004 to 0.2 μm thick.
