CONSTITUTION: A method for manufacturing a core-shell type supported catalyst comprises the following steps. A stabilizer allows a carbon supported element to be dissolved in a solution.

The carbon supported element with transition metals are filtered and washed. The carbon supported element is sprayed in the shell precursor solution. At a temperature of 60~80°C, a weak reducing agent is put into the solution and a metal ion of the shell precursor is reduced and obtained on the previously compounded transition metal.
