A catalyst particle (1) for a fuel cell according to the present invention includes: a metal particle (2) composed of either one of metal other than noble metal and an alloy of the metal other than the noble metal and the noble metal; and a noble metal layer (3) that is provided on a surface of the metal particle and has a thickness of 1 nm to 3.2 nm. By the fact that the catalyst particle for a fuel cell has such a configuration, the catalyst particle can enhance catalytic activity while reducing an amount of the noble metal. The catalyst particle (1) for a fuel cell according to the present invention can enhance the catalytic activity while reducing the amount of the noble metal.
