    摘要: The invention provides an aromatic polysulfone including an aromatic polysulfone having at least one highly polar functional group at its terminus, wherein in the aromatic polysulfone, an area of a signal attributed to the aromatic polysulfone having a highly polar functional group with respect to a total area of all signals attributed to the aromatic polysulfone in a chromatogram obtained by measurement through a gel permeation chromatography method under the following conditions is 0.1% or more and 11% or less, wherein the sample injection volume is 5 μL, column is “Shodex KF-803” manufactured by Showa Denko K.K., column temperature is 40° C., eluent is N,N-dimethylformamide, eluent flow rate is 0.5 mL/min, detector is ultraviolet-visible spectrophotometer (UV), and detection wavelength is 277 nm.
