PROBLEM TO BE SOLVED: To provide a method for producing a compound having an ester bond and/or amide bond, with a small content of impurities in high yield; and to provide a high purity compound obtained by the method.SOLUTION: There is provided a method for producing a mixed acid anhydride (4) by adding a compound (1) having at least one carboxy group and a base (2) simultaneously without mixing in advance to an acid halide compound (3) to react them. Also a method for producing an ester compound and/or amide compound (6) is provided which comprises: adding a compound (1) having at least one carboxy group and a base (2) simultaneously without mixing in advance to an acid halide compound (3) to react them to produce a mixed acid anhydride (4); and thereafter reacting with a compound (5) having at least one group selected from a hydroxy group, mercapto group and/or amino group.
