A roughened plated sheet including a roughened plated layer having a roughened nickel plated layer and a zinc plated layer formed on at least one surface of a metal substrate in this order from the metal substrate side, wherein a ten-point average roughness Rzjis of a surface of the roughened plated layer, according to laser microscope measurement, is 3 μm or more, and the metal substrate is a steel sheet.
Opening claim text (preview).
The invention claimed is: 1. A roughened plated sheet comprising a roughened plated layer having a roughened nickel plated layer and a zinc plated layer formed on at least one surface of a metal substrate in this order from the metal substrate side, wherein a ten-point average roughness RZ jis of a surface of the roughened plated layer, according to laser microscope measurement, is 3 μm or more, the metal substrate is a steel sheet, and the metal substrate is one selected from the group consisting of low carbon aluminum-killed steel, ultra-low carbon steel, and non-aging ultra-low carbon steel. 2. The roughened plated sheet according to claim 1 , wherein a lightness L* of a surface of the roughened plated layer is 83 or less. 3. The roughened plated sheet according to claim 1 , wherein a ten-point average roughness RZ jis of a surface of the roughened plated layer is 3 to 30 μm. 4. The roughened plated sheet according to claim 1 , wherein a lightness L* of a surface of the roughened plated layer is 45 to 83. 5. The roughened plated sheet according to claim 1 , further comprising another plated layer between the metal substrate and the roughened nickel plated layer. 6. The roughened plated sheet according to claim 5 , wherein the another plated layer is a nickel plated layer or a zinc plated layer. 7. The roughened plated sheet according to claim 1 , wherein an adhesion amount of the zinc plated layer forming the roughened plated layer is 3 g/m 2 or more. 8. The roughened plated sheet according to claim 1 , wherein the thickness of the metal substrate is 0.01 to 2.0 mm. 9. The roughened plated sheet according to claim 1 , wherein: the low carbon aluminum-killed steel has 0.01 to 0.15% by weight of carbon, the ultra-low carbon steel has 0.01% by weight or less of carbon, and the non-aging ultra-low carbon steel is obtained by adding Ti or Nb to an ultra-low carbon steel having 0.01% by weight or less of carbon.
