摘要： The present invention relates to a polyimide metal laminate which is a metal laminate comprising a stainless steel layer/a conductor layer/a polyimide resin layer/a metal layer, wherein the conductor layer is interposed between the stainless steel layer and the polyimide resin layer as a ground, and having a strong adhesion between the conductor layer and the polyimide resin layer, thus being able to be processed and used as a hard disk suspension. Specifically, the metal laminate of the present invention is characterized in that a surface of the conductor layer in contact with the polyimide resin layer is not smooth (preferably its 10-point average surface roughness is 0.5 μm or more).
