PROBLEM TO BE SOLVED: To provide a method for easily manufacturing an acrylic polymer having carboxyl group and/or acid anhydride group. SOLUTION: The method for manufacturing an acrylic polymer having carboxyl group and/or acid anhydride group comprises performing heating in which a resin temperature discharged from an evaporator is 240-280°C in a process for evaporating volatile components from a polymer solution comprising a (meth)acrylic polymer (A) having t-butyl acrylate and/or t-butyl methacrylate as essential components and an organic solvent.
