Provided is a shell, which comprises a metal substrate, a microarc oxidation layer and an outer coating, wherein the microarc oxidation layer is formed on the surface of the metal substrate and the outer coating is formed on the microarc oxidation layer; the outer coating comprises a coating layer and a metal layer both formed on the microarc oxidation layer. In addition, a method for manufacturing the shell is provided. The metal layer of the shell is formed on the microarc oxidation layer, and a strong adhesion force between the metal layer and the microarc oxidation layer enables the metal layer not to fall off easily.
