| abstract |
The present invention provides a Ni-plated metal plate, a welded structure, and a battery material which are excellent in weldability. A Ni-plated metal plate 2 is formed by forming a first Ni plating layer on a surface of a base material 2b made of a metal plate, and forming a second Ni plating layer thereon, and the thickness of the second Ni plating layer is 0.50 μm or more. Further, the total concentration of C and S in the second Ni plating layer from the surface to the depth of 0.4 μm is 1.0% by mass or less. |
