Electromagnetic wave generation due to electrostatic discharge from charged human body to an earthing electrode has been observed by the use of a pocketable size electrostatic discharge detector. A subject standing on an insulating platform to avoid additional stray capacity has been charged up to 13 kV of positive or negative voltage by a dc power supply. Electrostatic discharge from negatively charged human body has resulted more intensive electromagnetic wave than that from positively charged one. Magnitude of electromagnetic wave has depended on an inserted discharging resistance between the esrthing electrode and the ground. Electromagnetic wave detection rate has been defined, then V50; 50% electromagnetic wave detection voltage has been derived. The experimental results claims that a certain fraction of the power dissipated at electrostatic discharge should be radiated as Poynting vector of radiative electromagnetic noise.
