Provided is an electrode for a fuel cell and a method for manufacturing said electrode by which it is possible to increase the durability of a support and mitigate poisoning of catalyst particles by ionomers. The present invention includes at least: a step of heat treating, at a temperature of 1700 DEG C or greater and less than 2300 DEG C, a catalyst support, which is made of a mesoporous carbon in which the crystallite size (Lc) of the 002 surface is 1.5 nm or less; a step of supporting catalyst particles at least in the heat-treated catalyst support; and a step of covering ionomers in the catalyst support in which catalyst particles are supported.
