Abstract: An object of the present invention is to provide a method for producing an unsaturated carboxylic ester, wherein the risk of polymerization blockage is reduced and the required equipment cost and workload involved are kept low while maintaining a high conversion rate in an esterification reaction of unsaturated carboxylic acid. This object can be achieved by a method for producing an unsaturated carboxylic ester, which includes performing an esterification reaction using a reactor packed with a solid catalyst, wherein unsaturated carboxylic acid and alcohol are continuously fed to the reactor from an inlet thereof to form a fluid of the reaction solution in the reactor, and the vaporized organic solvent is continuously fed to the reactor from the inlet or a part near the inlet of the reactor.

Abstract: A ceramic filter includes a porous ceramic body which is a sintered body of ceramic particles, and a coating portion formed on a surface of each ceramic particle to support the catalyst. The porous ceramic body has a specific surface area equal to or greater than 0.5 m2/cc, measured by a mercury porosimeter, and an amount of the coating portion is equal to or greater than 15 g/l.
