PROBLEM TO BE SOLVED: To provide a method for manufacturing a catalyst carrying carrier that has a comparatively large particle size of a catalytic metal after being carried and has very few variations of the particle size, and to provide a method for manufacturing an electrode catalyst using the catalyst carrying carrier obtained by the above method, concerning a method of obtaining the catalyst carrying carrier by reducing and carrying the catalytic metal on a conductive carrier surface from a precursor of the catalytic metal.SOLUTION: The method is provided for manufacturing the catalyst carrying carrier 10, which is obtained by input of the conductive carrier 1 into a dispersion solvent, by input of an acid salt 2' and basic salt 3' of the catalytic metal, and by reducing and carrying the catalytic metals 2, 3 on the conductive carrier from the acid salt 2' and basic salt 3', respectively.
