Provided are non-halogen, flame-resistant, resin materials and resin magnet materials, and also electron beam controllers comprising the resin magnet materials. The resin material comprises (A) a non-halogen resin composition, (B) a metal oxide hydrate, and (C) one or both of antimony trioxide and zinc borate. The resin magnet material comprises those components (A), (B) and C), and (D) a magnetic material. In the electron beam controller, the four-pole and 6-pole convergence magnets and the two-pole purity controller magnets are made of the resin magnet materials. |
