Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for measuring a molecular weight of an aromatic polyether ketone represented by PEEK, that is easy and has a high reproducibility. SOLUTION: In a method for measuring a molecular weight of an aromatic polyether keytone by the gel permeation chromatography, a mixed solution of chlorophenol and halogenated benzene (the chlorophenol and the halogenated benzene are mixed in a solution at 20:80 to 60:40 (weight ratio)) is used as an eluent.
