PROBLEM TO BE SOLVED: To provide a method for manufacturing an acrylic polymerized molded body capable of manufacturing a foam molded body with reduced occurrence of voids and a method for manufacturing a foam molded body.SOLUTION: A method for manufacturing an acrylic polymerized molded body includes: the step (I) of heating and polymerizing a polymerizable solution containing an acrylic monomer, a chemical foaming agent, and a polymerization initiator so as to obtain a precursor molded body containing an unreacted monomer whose volume shrinkage with respect to a total volume of the polymerizable solution before polymerization is 14% or more; and the step (II) of heating the precursor molded body at a polymerization temperature higher than a polymerization temperature in the step (I) so as to polymerize the unreacted monomer and obtain an acrylic polymerized molded body. A rate of temperature increase when increasing the temperature of the precursor molded body until reaching the polymerization temperature in the step (II) is 4.0°C/hour or less. A method for manufacturing a foam molded body includes subjecting the acrylic polymerized molded body obtained in the foregoing manufacturing method to heat foaming.
