Abstract
A metal plate includes a surface including a longitudinal direction of the metal plate and a width direction orthogonal to the longitudinal direction. A surface reflectance by regular reflection of a light is 8% or more and 25% or less. The surface reflectance is measured when the light is incident on the surface at an angle of 45°±0.2°. The light is in at least one plane orthogonal to the surface.
