Compared with Pt / Pd / C catalyst has a equivalent thereto more catalytically active and provide the electrode catalyst that can contribute to cost reduction. Electrode catalyst 10A includes catalyst particles 3a to be supported on a carrier 2 and on the support. The catalyst particles have a core portion 4 formed on the carrier, a first shell portion 5a formed on the core portion, the second shell portion 6a which is formed on a portion of the surface of the first shell portion . The core unit includes a Pd, the first shell portion comprises a Pt, second shell portion comprises a Ti oxide. Furthermore, the electrode catalyst for the analysis region in the vicinity of the surface as measured by X-ray photoelectron spectroscopy, a ratio of Pt R1Pt (atom%), the proportion of Ti from the Ti oxide R1Ti (atom%) and is , formula (1): satisfies 1.00 ≦ (R1Ti / R1Pt) ≦ 2.50 condition.
