To provide a stainless steel cladded with an aluminum-nickel material which has excellent deep drawing property being a LDD of ≥ 2.0, its manufacturing method, and a battery case formed from the cladded stainless steel by deep drawing.

The stainless steel cladded with the aluminum-nickel material comprises a stainless steel layer 1 made of softened annealed stainless steel, a nickel layer 2 formed on one surface of the stainless steel layer 1 and composed of an Ni-based alloy including pure Ni or Ni as the main component, and an aluminum layer 5 which is diffusion-bonded to the surface of the nickel layer 2 via an Al-Ni intermetallic compound layer 4 and composed of an Al-based alloy including pure Al or Al as the main component. The thickness after the diffusion bonding of the Al-Ni intermetallic compound layer 4 is set to 0.5-2.0 μm. A nickel layer 3 can be formed on the other surface of the stainless steel layer 1 for improving corrosion resistance.
