Provided is a method for producing an aluminum-resin composite that can improve the adhesion between aluminum and a resin composition without using an adhesive and that can be easily treated with a waste liquid. The present invention relates to a method for producing an aluminum-resin composite as an electronic device part for mobile use. In the production method of the present invention, a roughening step of roughening the surface of the aluminum part with an etching agent and an adhesion step of attaching the resin composition to the roughened surface are performed. At least one of the etching agents is an alkaline etching agent containing amphoteric metal ions, nitrate ions, an alkali source, and a thio compound. [Selection] Figure 4 |
