    摘要: [Problem] The purpose of the present invention is to obtain a multifunctional (meth)acrylate with good yield by an ester exchange reaction of a polyhydric alcohol such as pentaerythritol or dipentaerythritol with a monofunctional (meth)acrylate. [Solution] A multifunctional (meth)acrylate manufacturing method characterized in that when manufacturing a multifunctional (meth)acrylate by an ester exchange reaction of a polyhydric alcohol with a monofunctional (meth) acrylate, catalyst (A) and catalyst (B) are used together. Catalyst (A) : One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure or salts or complexes thereof, amidines or salts or complexes thereof, and compounds with a pyridine ring or salts or complexes thereof. Catalyst (B): One or more kinds of compounds selected from a group consisting of zinc-containing compounds.
