The merits of U. H. V. E. M. (Ultra High Voltage Electron Microscope) and demands from metallurgical science are surveyed. The history of constructions of U. H. V. E. M. in Japan is reviewed briefly. It is mentioned that the utility of U. H. V. E. M. exceeds the predicted one. It is also applied to biological specimen and assured to be very useful in steroscopic observation of thick specimen. Japanese research groups equipped with U. H. V. E. M. are introduced. The outline of 3 MeV U. H. V. E. M. which is under construction in Japan is sketched. Finally, the problems of the future Mega-volts E. M., accelerating system, lens, observation and recording of E. M. image, are discussed.
