Disclosed is a palladium-containing catalyst which enables to produce an α,β-unsaturated carboxylic acid in high selectivity from an olefin or an α,β-unsaturated aldehyde. Also disclosed are a method for producing such a catalyst and a method for producing an α,β-unsaturated carboxylic acid using such a catalyst. Specifically disclosed is a palladium-containing catalyst containing 0.001 to 0.25 mole of antimony element to 1 mole of palladium element or a palladium-containing catalyst containing palladium element which composes a metal, tellurium element, and bismuth element.
