The metal-supported catalyst includes: a carbon carrier; and catalyst metal particles supported on the carbon carrier, wherein a ratio of number-average particle diameter of catalyst metal particles to average pore diameter of metal-supported catalyst is 0.70 or more and 1.30 or less, wherein, at relative pressure of a nitrogen adsorption isotherm of metal-supported catalyst within a range of 0.4 or more and 0.6 or less, maximum value of a ratio of a nitrogen adsorption amount of a desorption-side isotherm to a nitrogen adsorption amount of an adsorption-side isotherm is 1.05 or less, and wherein proportion of number of the catalyst metal particles each supported at a position having a depth of 20 nm or more from an outer surface of the carbon carrier to a total number of the catalyst metal particles supported on the carbon carrier is 11% or more.",
