Abstract
A jar can for a secondary battery is formed by deep-drawing a clad material prepared by bonding an aluminum sheet and an iron sheet to each other. A nickel layer is formed between the iron sheet and the aluminum sheet. Another nickel layer is formed on another surface of the iron sheet. Thus, a lightweight jar can for a secondary battery having high rigidity is obtained.
