And a metal plating layer 33 that does not generate a brittle intermetallic compound. Thus, the clad material of the present invention,
An insert material is interposed between the metal A and the metal B to join them.

Ａは圧延中に容易に接合する。The insert material 3 is made of metal A or metal B.
A metal plating layer 32 that does not form a brittle intermetallic compound with metal A and metal B on one surface of a thin plate 31 or 34 having the same composition as
Alternatively, in FIG. 1A, the metal plating layer 32 and the metal B are bonded during rolling without forming a brittle intermetallic compound, and the metal plating layer 32 and the thin plate 31 are The bonding strength is increased during rolling, and the thin plate 31 and the metal A having the same composition are easily bonded during rolling.
