Laminate for Suspension and Method for Producing Same

A laminate ( 20 ) for a suspension comprises a stainless steel foil ( 11 ), and an insulating layer ( 12 ) and a conductor layer ( 13 ) that are stacked in this order on the stainless steel foil ( 11 ). The stainless steel foil ( 11 ) contains a martensite phase in a volume fraction of 0.4 to 2.5 volume %. The insulating layer ( 12 ) is made of a polyimide resin, for example. The conductor layer ( 13 ) contains pure copper or a copper alloy, for example. The laminate ( 20 ) for a suspension is used for producing a wiring-integrated suspension that flexibly supports a slider including a magnetic head such that the slider is opposed to a recording medium.
