Abstract: The present disclosure provides a metal-resin composite and a method of preparing the same. The metal includes titanium or titanium alloy, the composite includes a metal substrate and a resin layer coated on at least part of surface of the metal substrate, a recess is distributed on the part of surface of the metal substrate coated with the resin layer, a part of resin of the resin layer extends downward to fill in the recess, a content of oxygen element on surface of the metal substrate is greater than 1wt%. The method includes dipping a metal substrate in an etching solution containing at least one alkali metal hydroxide so as to form a recess on surface of the metal substrate, and injecting a resin onto surface of the metal substrate after surface treatment sp as to form a resin layer. The metal-resin composite of the present disclosure is suitable for a shell of electronic product.
