Abstract:
The object of the present invention is to provide a metal plate having an excellent transportability. A maximum value of a steepness degree at a central area in a width direction of the metal plate is not more than 0.4%. In addition, the maximum value of the steepness degree at the central area is not more than a steepness degree at one end side area, and is not more than a steepness degree at the other end side area. Further, a difference between the maximum value of the steepness degree at the one end side area and the maximum value of the steepness degree at the other end side area is not more than 0.4%.
