PROBLEM TO BE SOLVED: To provide a clad material and manufacturing method thereof which enable manufacturing efficiently a clad material with two or more metal materials arranged and joined together in parallel in the longitudinal direction and allow improvement of the joint strength, productivity, the yield and reduction in production costs. SOLUTION: The clad materials 10 and 30 consist of two or more metal materials 11 and 12 or 31 and 32, respectively, having different properties and arranged and joined together in the longitudinal directions. A convex part 13 or 33 is formed, respectively, in an end of one metal material 11 or 31, and a concave part 14 or 34 is formed, respectively, in the other metal material 12 or 32 so as to sandwich the convex part 13 or 33 from the upper and lower sides.
