The present disclosure relates to a heat transfer tube having rare-earth oxide deposited on a surface thereof and a method for manufacturing the same, in which the rare-earth oxide can be deposited on the surface of the heat transfer tube to implement a superhydrophobic surface even under the high temperature environment and a plurality of assembled heat transfer tubes can be coated by coating a complex shape by depositing rare-earth oxide using a method for dipping a surface of the heat transfer tube and coating the same, thereby reducing or preventing the heat transfer tubes from being damaged during the assembling of the heat transfer tubes after the coating.
