A clad plate 1 in which a metal material layer 3 and an aluminum layer 4 are firmly joined together by rolling and which does not cause rough surface after press working at a surface of the metal material layer 3 due to the aluminum layer 4 in which crystal grains have grown large due to heat softening processing is provided with a first layer 3 and a second layer 4. The first layer 3 is made of ferrite-based stainless steel, and the second layer 4 is made of aluminum. In a range of the second layer 4 from a first joining interface 6 to a position at a distance of 100 μm in a plate thickness direction, the area ratio of the crystal grains having an aspect ratio of 2.0 or less is 85% or more, the aspect ratio representing the ratio of a major axis to a minor axis, and a maximum crystal grain size is 50 μm or less. In addition, at a half position in the plate thickness direction of the second layer 4, the area ratio of the crystal grains having an aspect ratio of 2.0 or less is less than 50%.
