A paint film structure formed on an aluminum member or aluminum alloy member has a first paint film layer formed on a surface of the aluminum member or aluminum alloy member and a second paint film layer formed on a surface of the first paint film layer, the first and second paint film layers being chiefly composed of a colloidal silica, an organoalkoxysilane part hydrolysis condensation product, and a polymer or copolymer of an unsaturated ethylenic monomer, polymeric content or copolymeric content of the unsaturated ethylenic monomer in the first paint film layer being less than polymeric content or copolymeric content of the unsaturated ethylenic monomer in the second paint film layer.
