Abstract
An object of the present invention is to provide a production method for efficiently producing a metal laminate having high bonding strength. A method for producing a metal laminate material comprising the steps of: sputter etching faces to be bonded of a stainless steel and an aluminum such that an oxide layer remains on each face; temporarily bonding the faces to be bonded of the stainless steel and the aluminum by roll pressure bonding; and thermally treating the temporarily bonded laminate material at a temperature lower than the recrystallization temperature of the stainless steel to thermally diffuse at least a metal element comprised in the stainless steel into the aluminum.
