PROBLEM TO BE SOLVED: To provide a method for producing a purified green tea extract capable of efficiently easily removing turbid components contained in a green tea extract, to provide the purified green tea extract produced by the method, and to provide packaged drink containing the purified green tea extract. SOLUTION: This method for producing the purified green tea extract which contains 36-99 mass% of nonpolymerized catechin in solid comprises obtaining a green tea extract by subjecting a green tea extract to contact treatment with a mixed solution having a mass ratio of an organic solvent to water of (65:35)-(99:1) and activated carbon and/or acid clay or activated clay, and separating the turbid content precipitated after adjusting a mass ratio of the organic solvent to water in the solution to (0:100)-(85:15).
