Zusammenfassung:	The purpose of the present invention is to provide a method for producing a (meth)acrylic monomer that suppresses heterogeneity of a (meth)acrylic resin depolymerization system and that makes it easier for microwaves to reach the system interior efficiently. According to this method for producing a (meth)acrylic monomer, which includes a step 1 for irradiating a prepared (meth)acrylic resin with microwaves and mixing to obtain a melt containing a (meth)acrylic resin having reduced molecular weight, a step 2 for adding additional (meth)acrylic resin to the melt and mixing to obtain a mixture containing additional (meth)acrylic resin in the melt, and a step 3 for irradiating the mixture with microwaves and mixing to obtain a (meth)acrylic monomer, it is possible to suppress heterogeneity of the (meth)acrylic resin depolymerization system and to make it easier for microwaves to reach the system interior efficiently.
