Outline of Final Research Achievements

Japan's world-leading success in the development of the high voltage electron microscope was due to the continuous development research from the Subcommittee 37 of the Japan Society for the Promotion of Science, which began before World War II. Even after the Subcommittee ended after the war, researchers and engineers completed the development of the 300kV electron microscope by the mid-1950s through industry-academia collaboration. Ten years later, the 500kV high voltage electron microscope was developed, and commercial machines were completed and exported overseas. Basic and applied research using the high voltage electron microscope was also actively pursued by research institutes in Japan. This was made possible largely due to the financial support provided by the Ministry of Education.

Academic Significance and Societal Importance of the Research Achievements

超高圧電子顕微鏡の開発過程を詳細に辿ることを行い、日本でなぜ開発に成功したかを明らかにした。科学機器の開発には機器を利用した基礎研究および応用研究を並行して展開していくことも重要であることも明らかになった。文部省の金銭的支援もこうした研究には有効であった。1950年代から60年代に進められた産学官連携による開発の知見は今後の産学官連携の推進にも役立つであろう。
