Abstract
An object of the present invention is to obtain a composite in which a copper or copper alloy is securely integrated with and joined to PBT or PPS. A copper product that has been suitably roughened by chemical etching and also blackened can be used favorably. A surface-treated copper pieceis inserted into a cavity formed by a movable molding plateand a stationary molding plateof an injection molding mold, and a specific resin is injected to obtain an integrated product. PBT or PPS can be used as the resin component of a resin compositionthat is used here. High injection joining strength is obtained if the resin composition contains, as an auxiliary component, PET and/or a polyolefin resin in the case of PBT, and a polyolefin resin in the case of PPS.
