Abstract
A first layer (11) and a second layer (12) are layered with an intermediate layer (21) therebetween. A clad material (1) is manufactured by heating and bonding the layered body at a temperature, at which the ratio of the mass of a liquid phase generated from the intermediate layer (21) is 5% or more and 35% or less, and by rolling the body. The clad material may comprise the clad material (1) which is a two-layer material formed of the first layer (11) and the second layer (12) as described above, as well as a third layer, a fourth layer, a fifth layer, and the like.
