Abstract (in Japanese) (See Japanese page) 
(in English) In the power supply to the semiconductor on PCB, we verified that the radiation noise can be reduced by forming power and ground opposite site, and that the transfer impedance (Z21) is effective as this parameter. Moreover, we verified reduction of the radiation noise by using a bypass capacitor together. By forming the power supply GND opposing part, and, by adding the bypass capacitor, it is possible to reduce the radiation noise of the power supply system. Further, radiation noise has been found to have a correlation with the Z21.
