description The present invention relates to a catalyst for solid polymer fuel cells in which catalyst particles including platinum or platinum alloy are supported on a carbon powder carrier. The catalyst of the present invention is a catalyst for solid polymer fuel cells in which the bond energy (Ec) at a gravity center position is 2.90 eV or more and 3.85 eV or less as calculated from a spectrum area of a Pt5d orbit-derived spectrum which is obtained by measuring a valence band spectrum in a range of 0 eV or more and 20 eV or less in the result of subjecting the catalyst particles to X-ray photoelectron spectroscopic analysis.
