The present invention provides a (meth)acrylate manufacturing method characterized in that when manufacturing a (meth)acrylate by an ester exchange reaction between an alcohol and a monofunctional (meth)acrylate using catalyst A and catalyst B together, contact treatment of the ester exchange reaction product with adsorbent C is performed. Catalyst A: One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure and salts or complexes thereof, amidine and salts or complexes thereof, compounds with a pyridine ring and salts or complexes thereof, phosphines and salts or complexes thereof, and compounds with a tertiary diamine structure and salts or complexes thereof. Catalyst B: One or more kinds of compounds selected from a group consisting of compounds comprising zinc. Adsorbent C: One or more kinds of compounds selected from a group consisting of oxides and hydroxides comprising at least one of magnesium, aluminum and silicon.
