Abstract (in Japanese) (See Japanese page) 
(in English) Impulsive electromagnetic noise is caused by ESD. Especially, micro gap discharge of less than 1kV produces GHz band width electromagnetic noise. It is thought ESD noise has possibility that affects to various electrical systems. To solve EMC problems, we elucidated a mechanism which ESD noise occurs. We found out the amplitude of electromagnetic noise depended on the size of electrode and applied voltage of the electrode in a previous study. Therefore, we mainly measured the amplitude of electromagnetic noise when we changed the approach speed of electrode, and measured the amplitude of electromagnetic noise when we changed the surface roughness of electrode by this experiment. Then, the average amplitude and the dispersion of the amplitude tended to increase with the approach speed became fast. Furthermore, the relationship between surface roughness of electrode and received voltage was examined. The received voltage decreased approximately 20 % in the surface roughness of electrode from 3 micro meter to 22 micro meter.
