Abstract
[Problem] To provide: a roll-bonded body which is able to be suppressed in waviness in the surface; and a method for producing this roll-bonded body. [Solution] A roll-bonded body according to the present invention is obtained by bonding a first metal layer and a second metal layer with each other by means of rolling, and is characterized in that the surface of the first metal layer has an arithmetic average waviness (Wa) 0.01-0.96 and a maximum waviness height (Wz) of 0.2-5.0 μm.
