Abstract: An electrode catalyst for fuel cells that can inhibit an increase in gas diffusion resistance includes a carbon material having a ratio of a peak intensity IA derived from an amorphous structure to a peak intensity IG derived from a graphite structure in an X-ray diffraction spectrum (ratio IA/IG) of 0.90 or less as a catalyst-supporting carrier.
