Abstract
The method is for manufacturing a clad material (30), which includes: clad rolling for rolling and bonding a first metal plate (131) made of stainless steel, a second metal plate (132) made of Cu or a Cu alloy, and a third metal plate (133) made of stainless steel in a state in which the first metal plate, the second metal plate, and the third metal plate are stacked in this order. The clad rolling is performed with a pressure-bonding load of 4.4×103 N/mm or more. The second layer is made of Cu or a Cu alloy. The third layer is made of stainless steel. The clad material has an overall thickness of 1 mm or less.
