description	A porous carbon and a method of manufacturing the same are provided, which can inhibit metal particles from being oxidized and can keep the effect obtained by adding the metal particles for a long period of time by allowing the metal particles to disperse sufficiently. The method is characterized by comprising the steps of: mixing a polyamic acid resin varnish 1 as a carbon precursor, magnesium oxide 2 as template particles, and chloroplatinic acid 6 as a metal salt; heat-treating the mixture in a nitrogen atmosphere at 1000°C for 1 hour to reduce the chloroplatinic acid into platinum and thermally decomposing the polyamic acid resin to prepare a carbon 3 containing the platinum particles 7; and washing the resulting carbon 3 with a sulfuric acid solution added at a concentration of 1 mol/L to completely dissolve MgO away.
