<p>PURPOSE: A method for manufacturing a supported catalyst and the supported catalyst obtained thereby are provided to improve the yield of carbon nanotubes and to reduce the capacity of a reactor by reducing the consumption of a metal aqueous solution. CONSTITUTION: A method for manufacturing a supported catalyst comprises a first supporting step, a low temperature firing step, a second supporting step, and a high temperature firing step. The first supporting step allows a support to be in contact with a metal aqueous solution containing a catalytic component and an active component. The low temperature firing step is performed at the temperature of 300-450°C. The second supporting step allows the low temperature fired catalyst to be in contact with a metal aqueous solution containing a catalytic component and an active component.
