PROBLEM TO BE SOLVED: To provide a resin bonding method for bonding a polyester resin to an epoxy-based adhesive, having excellent adhesiveness. SOLUTION: The method is for bonding a polyester resin 2 to an epoxy-based adhesive 3. The epoxy-based adhesive 3 is bonded to an adhesive surface 202 after surface treatment for providing the surface 201 of the polyester resin 2 with an oxygen-containing functional group. The oxygen-containing functional group is a hydroxy group, a carbonyl group or a carboxy group. The method is for bonding the polyester resin 2 after annealing treatment to the epoxy-based adhesive 3. The oxygen-containing functional group is formed in an area in thickness of 3-10 nm from the surface 201 of the polyester resin 2. COPYRIGHT: (C)2008,JPO&INPIT
