Abstract (in Japanese) (See Japanese page) 
(in English) Amplitude properties of radiated electromagnetic field caused by low voltage ESD (electrostatic discharge) in spherical electrode was examined by experimental study. The micro-gap discharge as the low voltage ESD shows very fast transition-duration of about 32 ps or less, and potential gradient in electrode gap was very high of about 80 MV/m when the breakdown. Also, a relationship between the potential gradient in a gap and the radiated electromagnetic field was measured in a resonant experimental system using the electrode of dipole configuration. In this time, we present an improved experimental system to measure the radiated electromagnetic filed in more wideband region using spherical electrodes and a horn antenna. In this experiment, the amplitude of radiated electromagnetic field was expressed by an output voltage of the horn antenna. As a consequence, the amplitude of radiated field was proportion to the discharge voltage in from 300V to 620V. And so, the amplitude of radiated electromagnetic field was proportion to the diameter of the spherical electrode in the wideband experimental system.
