Threaded parts such as bolts are rust-proofed by using a treatment liquid including a binder resin containing silica and at least one of a modified epoxy resin obtained by graft polymerization using a carboxylic acid-containing acrylic polymer as a side chain and a modified acrylic resin obtained by graft polymerization using a carboxylic acid-containing acrylic polymer as a side chain. By using this treatment liquid, coating treatment can be carried out at one time without need to use an organic solvent. There is an advantage that the friction coefficient does not increase even when tightening is repeated.

A metal-and-resin composite includes a metal substrate having a plurality of nano pores, an intermediate layer formed on the metal substrate, and a resin member. The intermediate layer fills at least portion of each nano pore. The resin member covers and bonds with the intermediate layer, thus to bond with the metal substrate.
