摘要：
To provide electrode catalyst (core-shell catalyst) having an excellent catalyst activity which contributes to lower the cost of the PEFC. The electrode catalyst has catalyst particles supported on a support. The catalyst particle has a core part containing simple Pd and a shell part containing simple Pt. A percentage R C (atom%) of the carbon of the support and a percentage R Pd (atom%) of the simple Pd in an analytical region near a surface measured by X-ray photoelectron spectroscopy (XPS) satisfy the conditions of the following equation (1): 2.15 ‰¤ [100 x R Pd / (R Pd +R C )].
