A magnetic head suspension, wherein the interconnection wiring is integrated with a spring-like metal suspension member, is manufactured by first preparing a laminated plate comprised of a flexible insulating base sandwiched between a resilient metal layer and a layer of an electrical conductor. The electrical conductor layer and resilient metal layer are respectively formed into the desired circuit wiring pattern and a suspension member, unnecessary portions of the insulating base are removed, the wiring pattern is provided with a protective layer and the suspension member is mechanically formed into a desired final configuration.
