Beschreibung
Zusammenfassung:	[Problem to be Solved] To provide a catalyst particle including Pt and Pd, a support-type catalyst particle in which the catalyst is supported, and the like, which have a high oxygen reduction activity and a low methanol oxidation activity. [Solution] A catalyst particle including platinum and palladium, and having a proportion of palladium in the surface of the particle, measured by X-ray photoelectron spectroscopy (XPS), of 45 to 55 atom% with respect to a total amount of platinum and palladium of 100 atom%.
