The present invention is an acrylic acid polymer of a low molecular weight having a narrow molecular weight distribution, the present invention relates to a production method for obtaining more efficiently without using a large amount of chain transfer agent. In the continuous production method of the acrylic acid-based polymer obtained by polymerizing a monomer of acrylic acid as essential components in a row, characterized in that given a mechanical load of 0.5 to 2.5kJ / L in the liquid outlet of the reactor by a liquid sending pump. In the high molecular weight component is reduced in accordance with, dispersibility and the like are obtained acrylic acid-based polymer is excellent for low molecular weight.
