An electromagnetic noise suppressor of the present invention has magnetic resonance frequency of 8 GHz or higher, and the imaginary part of complex magnetic permeability at 8 GHz is higher than the imaginary part of complex magnetic permeability at 5 GHz. Such an electromagnetic noise suppressor is capable of achieving sufficient electromagnetic noise suppressing effect over the entire sub-microwave band. The electromagnetic noise suppressor can be manufactured by forming a composite layer on the surface of a binding agent through physical deposition of a magnetic material on the binding agent. The structure with an electromagnetic noise suppressing function of the present invention is a printed wiring board, a semiconductor integrated circuit or the like that is covered with the electromagnetic noise suppressor on at least a part of the surface of the structure.

The invention provides a transmission noise suppressing structure and a wiring board capable of suppressing a transmission noise transferred through a power supply line, stabilizing a power supply voltage, and reducing signal transmission line cross talk transmitted through the power supply line or a ground layer without being affected by a resistive layer. A transmission noise suppressing structure includes a power supply line and a signal transmission line arranged apart from each other on the same surface; a ground layer arranged apart from the power supply line and the signal transmission line; and a resistive layer arranged apart from the power supply line and the ground layer. The resistive layer has an area (I) which faces the power supply line and an area (II) which does not face the power supply line. The resistive layer and the signal transmission line are apart from each other.
