PROBLEM TO BE SOLVED: To provide a method for producing a dialkylaminoalkyl (meth)acrylate quaternary salt with which a quaternizing agent can stably be fed without flowing thereof back to a feed pipe and has excellent solubility in a reaction liquid and the high-purity dialkylaminoalkyl (meth)acrylate quaternary salt can be produced with high productivity. SOLUTION: The method for producing the dialkylaminoalkyl (meth)acrylate quaternary salt comprises continuously feeding a dialkylaminoalkyl (meth)acrylate, the quaternizing agent and water to a reactor and continuously taking out the reaction liquid in the reactor. In the method, the quaternizing agent is fed with an ejector. COPYRIGHT: (C)2004,JPO
