Provided is a method of producing a purified chlorogenic acid-containing composition, including: a first step of dispersing or dissolving a raw material chlorogenic acid-containing composition in an aqueous solution of organic solvent； a second step of removing a precipitate from a dispersion or a solution obtained in the first step； and a third step of bringing a solution obtained in the second step into contact with activated carbon including activated carbon (A) having a pore volume of from 0.3 mL/g to 1.0 mL/g and activated carbon (B) having a pore volume larger than that of the activated carbon (A), in which a difference [(B)−(A)] in pore volume between the activated carbon (A) and the activated carbon (B) is from 0.1 mL/g to 1.5 mL/g.
