The invention discloses a metal base subjected to surface treatment and a preparation method thereof. The metal is aluminum or an aluminum alloy. The metal base comprises a metal base and a hard anodic oxide film layer adhering to at least one part of the surface of the metal base. The surface of the hard anodic oxide film layer is provided with first etch pits. The invention also provides a metal-resin compound. The metal is aluminum or an aluminum alloy. The metal-resin compound comprises the metal base subjected to surface treatment and a resin layer coating at least one part of the surface of the metal base, wherein a part of resin in the resin layer extends downward and fills the etch pits of the metal base. In the metal-resin compound, bonding strength between the resin and the metal base is high and the resin layer does not easily fall from the metal base surface so that the metal-resin compound has high structural stability, satisfies high structural stability requirements of a use field and can be used as an electronic product housing.
