PURPOSE: To provide a weld bond joining method capable of obtaining the sufficient welding strength even before the heat treatment hardening of the adhesive by improving the adhesive to be used in the weld bond joining method. CONSTITUTION: In the weld bond joining method where the adhesion and the resistance spot welding are jointly used, the adhesive to be used in the adhesion has the composition consisting of, by volume, l-15% of one or two or more kinds of the conductive metal, metallic oxide, metallic carbide, metallic nitride, metallic boride, or metallic silicate of powder whose grain size is <=10μm, of piece or flake shape whose thickness is >=0.5μm and whose size is 30μm in the thermosetting epoxy resin consisting of the epoxy resin and the latent hardening agent. This adhesive is used for the joining in the weld bond joining method.
