Abstract
A method of manufacturing a magnetic head suspension having a circuit wiring pattern member, comprises the steps of: preparing a laminated plate composed of a flat flexible insulating base member (2), a conductive layer (9 or 3) formed on one surface thereof, and an elastic metal layer (8 or 1) formed on the other surface thereof; photo-etching the conductive layer of the laminated plate, to form a metal mask (9) of a desired flexible insulating base member shape; removing the exposed flexible insulating base member (2) to such a thickness that the elastic metal layer (8 or 1) is at least not exposed; photo-etching the formed metal mask (9), to form a desired circuit wiring pattern (3); further etching the flexible insulating base member (2), to remove a part of the flexible insulating base member (2) still remaining on the surface of the elastic metal layer (8 or 1) in the preceding step, by using the formed circuit wiring pattern (3) as a mask; forming a surface protecting layer (4) on the surface of the formed circuit wiring pattern (3) and photo-etching the elastic metal layer (8) and bending the photo-etched elastic metal layer (8) to a desired shape, to form a suspension (1) of a desired shape.
