Zusammenfassung:To provide a clad with excellent peel strength.SOLUTION: In a clad in which two or more layers of different metallic materials are laminated in a plate thickness direction, a layer on one or both surfaces of the clad is a stainless steel in which the metallic material has a thickness of 0.03 mm or more, an average value of a nitrogen amount in an area of ±0.005 mm from a center in a thickness direction of the layer comprising the stainless steel is 0.01 to 0.3 mass%, an average value of a nitrogen amount in an area of 0.01 mm from both ends in the thickness direction exceeds 1.30 times of the average value of the nitrogen amount in the area of ±0.005 mm from the center in the thickness direction.SELECTED DRAWING: None 【課題】剥離強度に優れるクラッドを提供する。【解決手段】異なる金属材料が板厚方向に2層以上積層されたクラッドであって、クラッドの一方又は両方の表面の層は金属材料が厚さ0.03mm以上のステンレス鋼であり、ステンレス鋼である前記層の、厚さ方向の中心から±0.005mmの領域における窒素量の平均値が0.01〜0.3質量%であり、厚さ方向の両端から0.01mmまでの領域における窒素量の平均値が、厚さ方向の中心から±0.005mmの領域における窒素量の平均値の1.30倍超であることを特徴とするクラッド。【選択図】なし
