Provided is an electrically-insulating resin composition containing a polyamide-imide resin, silica fine particles, and a dispersant having a phosphate ester group. By using said electrically-insulating resin composition, it is possible to provide an electrical insulator having excellent withstand voltage life characteristics against a surge voltage. L'invention concerne une composition de résine électriquement isolante contenant une résine polyamide-imide, des particules fines de silice et un dispersant ayant un groupe ester de phosphate. En utilisant ladite composition de résine électriquement isolante, il est possible d'obtenir un isolant électrique ayant d'excellentes caractéristiques de durée de vie en tension de tenue contre une surtension. ポリアミドイミド樹脂と、シリカ微粒子と、リン酸エステル基を有する分散剤とを有する電気絶縁樹脂組成物。この電気絶縁樹脂組成物を使用して、サージ電圧に対して優れた耐電圧寿命特性を有する電気絶縁体を提供することができる。
