The present invention is process of preparing unsaturated carboxylate continuously from unsaturated aldehyde, and the process includes the step of preparing catalyst and the step of oxidizing and esterifying unsaturated aldehyde in the presence of the prepared catalyst to prepare unsaturated carboxylate continuously. The catalyst is supported catalyst with carried Pd, Pb and/or Bi and at least one of Fe, Zn, Ge and La. In the presence of the catalyst and molecular oxygen and through continuous operation in a fixed bed, unsaturated aldehyde is oxidized and esterified directly with methanol into unsaturated carboxylate. The present invention has effectively lowered Pd content in the catalyst, lowered production cost, mild reaction condition, simple operation, high product selectivity, easy regeneration of the catalyst and other advantages.
