To provide a high strength catalyst and a producing method of a carboxylic ester using the same.

A crystalline metallosilicate expressed by xM2/nO.ySiO2.R2/w as the composition of the anhydride expressed by the molar ration of the oxides is used as a carrier. The palladium-containing deposited catalyst for producing the carboxylic ester by allowing an aldehyde to react with an alcohol in the presence of oxygen and the producing method for the carboxylic ester using the catalyst are provided. In the formula, M expresses at least one kind of a n-valent cation, R represents at least one kind of a w-valent metal selected from among group Ib, group IIb, group IIIa, group IIIb, group IVa, group IVb, group Va, group Vb, group VIb, group VIIb, group VIII in Periodic table, 0.3≤x≤2.5 and 0.6≤y≤500.
