An aromatic polysulfone resin which has repeating units represented by formula (I) and formula (II) and in which the ratio (m:n) of the molar content (m) of the repeating units represented by formula(I) and the molar content (n) of the repeating units represented by formula (II) is 1:2000-1:200. (The hydrogen atoms in the phenylene groups of formula (I) and formula (II) may each independently besubstituted by alkyl groups, aryl groups, or halogen atoms.) 一种芳香族聚砜树脂，其具有由下述式(I)和下述式(II)表示的重复单元，由所述式(I)表示的重复单元的摩尔含量(m)与由所述式(II)表示的重复单元的摩尔含量(n)的比(m：n)为1：2000～1：200。(所述式(I)和所述式(II)的亚苯基中的氢原子可以分别独立地被烷基、芳基或卤素原子取代。)。
