The purpose of the present invention is to provide a metal plate having good conveyance properties. The maximum steepness value in a central portion in the width direction of a metal plate is 0.4% or less. Further, the maximum steepness value in the central portion is no more than the maximum steepness value in one end side portion, and is no more than the maximum steepness value in the other end side portion. Furthermore, the difference between the maximum steepness value in the one end side portion and the maximum steepness value in the other end side portion is 0.4% or less.
