Housing, terminal device, and housing manufacturing method

A housing, comprising:

• a magnesium-based metal matrix;
• a first aluminum-based metal layer and a second aluminum-based metal layer are respectively disposed on two sides of the magnesium-based metal matrix;
• a first metal layer comprising copper, titanium, nickel, cobalt, tantalum, zinc, or silver, the first metal layer disposed between the magnesium-based metal matrix and the first aluminum-based metal layer;
• an anodic oxidation layer, an electrophoresis layer, or an ink-jet printing layer disposed on a surface of a side that is of the first aluminum-based metal layer and that is away from the first metal layer;
• a second metal layer comprising copper, titanium, nickel, cobalt, tantalum, zinc, or silver, the second metal layer disposed between the magnesium-based metal matrix and the second aluminum-based metal layer;
• and
• a conductive surface defining electrical connection pads disposed on a surface of a side that is of the second aluminum-based metal layer and that is away from the second metal layer.
