Herein disclosed is a liquid homogenizer for mixing two or more liquids, comprising: a rotator (1) rotatable around a rotation axis; at least two liquid-mixing chambers (6, 10) formed in the rotator, and being different from each other in distance from the rotation axis; and at least two channels (8) through which one of the liquid-mixing chambers is communicated with the other of the liquid-mixing chambers (6, 10), wherein the liquid-mixing chambers (6, 10) include an outer liquid-mixing chamber (10) and an inner liquid-mixing chamber (6) close to the rotation axis in comparison with the outer liquid-mixing chamber, when the rotator (1) is rotating around the rotation axis, the liquids are shifted by a centrifugal force to the outer liquid-mixing chamber from the inner liquid-mixing chamber through the channels (8), and agitated to be mixed by turbulent flows in the outer liquid-mixing chamber.
