<P>PROBLEM TO BE SOLVED: To provide a catalyst for manufacturing α,β-unsaturated carboxylic acid with high productivity from olefin or α,β-unsaturated aldehyde, to provide a manufacturing method of the catalyst and to provide a manufacturing method of α,β-unsaturated carboxylic acid using the same. <P>SOLUTION: The palladium-containing catalyst is manufactured so that the catalyst contains 0.001-0.15 mols of platinum element per 1.0 mol of palladium element. The catalyst is used for manufacturing α,β-unsaturated carboxylic acid. Further, it is preferable that the catalyst contains 0.001-0.40 mols of tellurium element per 1.0 mol of palladium element. <P>COPYRIGHT: (C)2009,JPO&INPIT |
