Patent ID: 7964975

Claim:
A fabrication method for a metal-base/resin bonded structured body, including the steps of: (1) applying, to a surface of the metal base, a solution containing an organometallic compound decomposable at 350° C. or lower, wherein the metal of the organometallic compound has a free energy of oxide formation less than that of a surface material of the metal base and a ligand of the organometallic compound is selected from a group consisting of 2-ethylhexanoate, neodecanoate, octylic acid, methacrylic acid, acrylic acid, naphthenic acid, acetate, and diethyl compounds; (2) baking the applied solution in an oxidizing atmosphere to form, on the surface of the metal base, a coating containing an oxide of the metal of the organometallic compound; (3) providing the resin on the coating; and (4) hardening the resin to provide the metal-base/resin bonded structured body.
