Roll-bonded laminate and method for producing the same

A method for producing a roll-bonded laminate, comprising:

• subjecting a surface of a stainless steel plate and a surface of an aluminum alloy plate to be bonded to each other to sputter etching, wherein the aluminum alloy plate contains one or more additive metal elements selected from Mg, Mn, Si, and Cu, the total content of the additive metal elements exceeds 1% by mass, and a peel strength of the roll-bonded laminate is 60 N/20 mm or higher, and wherein the aluminum alloy plate has a thickness of 0.01 mm to 2.5 mm;
• pressure bonding the surfaces subjected to sputter etching to each other at a reduction ratio of the aluminum alloy plate of 5% or higher and a reduction ratio of the roll-bonded laminate of 15% or lower;
• and
• performing batch annealing at 200° C. to 370° C. or continuous annealing at 300° C. to 800° C.
