Disclosed is a method for producing an electrode catalyst for a fuel cell, which comprises a Ru-containing metal microparticle supported on an electrically conductive carbon carrier, wherein M2RuX6 [M=at least one member selected from H, Li, Na, K and NH4; X=at least one member selected from Cl, Br, I and NO3] is used as a precursor of Ru. It becomes possible to produce an electrode catalyst for a fuel cell, which is improved in the methanol oxidation activity per mass or surface area of the catalyst compared with a conventional Pt- and Ru-carrying carbon catalyst prepared by using a Ru raw material having an average valency of 3.
