Provided is a printed wiring board having a conduction noise suppressing function. In a printed wiring board (10), a printed wiring board main body (20) wherein conductor layers (a power supply layer (24), a signal transmission layer (26), a ground layer (28)) are formed on the surfaces of a substrate (22), and a coverlay film (30) wherein a resistor layer (34) is formed on a surface of a coverlay film main body (32)are bonded to each other with an adhesive layer (40) therebetween. The resistor layer (34) is arranged to face the conductor layers (the power supply layer (24), the ground layer (28)) by being spaced apart from the conductor layers with the adhesive layer (40) between the resistor layer and the conductor layers. |
