Zusammenfassung:An aromatic polyester having a repeating unit represented by formula (1) shown below and a terminal structural unit represented by formula (1e) shown below, wherein the proportion of the terminal structural unit per unit mass of the aromatic polyester is not more than 50 µmol/g.        -O-Ar1-CO- ...     (1)        -O-Ar1-CO-OH ...     (1e)(In the formulas, Ar1 represents a 1,4-phenylene group, a 2,6-naphthylene group or a 4,4'-biphenylylene group. The hydrogen atoms that exist in the groups represented by Ar1 may each be independently substituted with a halogen atom, an alkyl group or an aryl group.)
