Summary:To provide a scanning electromagnet that makes it possible to reduce a gap between magnetic pole parts.SOLUTION: A vacuum structure 100 is configured so that gap formation surfaces 70a, 70a are arranged in a vacuum. In this case, a gap GP formed between the gap formation surfaces 70a, 70a itself is made to be a vacuum space. Accordingly, a requirement for arrangement of a vacuum formation duct 200 (refer to Fig. 6) in the gap GP is eliminated, which makes it possible to reduce the gap GP.SELECTED DRAWING: Figure 5 【課題】磁極部の間のギャップを小さくすることが可能となる走査電磁石を提供する。【解決手段】真空構造１００は、ギャップ形成面７０ａ，７０ａを真空中に配置するように構成されている。この場合、ギャップ形成面７０ａ，７０ａ同士の間に形成されるギャップＧＰ自体が真空な空間となる。従って、ギャップＧＰに真空形成用のダクト２００（図６参照）を配置する必要がなくなるため、当該ギャップＧＰを小さくすることが可能となる。【選択図】図５
