Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a catalyst, by which the catalyst whose activity is restrained from being deteriorated with time due to carbon monoxide poisoning can be manufactured at the cost lower than before and to provide the catalyst obtained by this manufacturing method. SOLUTION: The catalyst is a conjugated catalyst of platinum or a platinum-based alloy with carbon and is characterized in that a peak of a 4f orbit of the platinum or platinum-based alloy of the multiplexed catalyst, which is measured by using a device for X-ray photoelectron spectroscopic analysis, is shifted to the high energy side by 0.01-0.40 eV. The method for manufacturing the catalyst comprises a step of depositing a film of such a state that platinum or the platinum-based alloy is conjugated with carbon by a PVD (physical vapor deposition) method or a CVD (chemical vapor deposition) method while introducing a carbon source into platinum or the platinum-based alloy.
