The invention discloses a metal-resin composite body and a preparation method thereof. The metal is titanium or a titanium alloy. The composite body includes a metal base material and a resin layer attached to at least part of the surface of the metal base material. There are pits distributed on the surface of the metal substrate of the layer, part of the resin in the resin layer extends downwards and fills the pits, and the oxygen element content of the surface layer of the metal substrate is more than 1% by weight. The preparation method comprises immersing the metal substrate in an etching solution containing at least one alkali metal hydroxide, forming pits on the surface of the metal substrate; injecting a resin into the surface of the obtained surface-treated metal substrate to obtain A resin layer is formed. In the metal-resin composite of the present invention, the bonding force between the metal substrate and the resin layer is high, the resin layer is not easy to fall off from the surface of the metal substrate, and is suitable for use as an electronic product casing. The etching solution used in the preparation method of the invention has low toxicity and low volatility, high operation safety and little environmental pollution.
