Abstract

The present invention provides a nickel-plated heat-treated steel sheet for a battery can (), having a nickel layer with a nickel amount of 4.4 to 26.7 g/mon a steel sheet (), wherein when the Fe intensity and the Ni intensity are continuously measured along the depth direction from the surface of the nickel-plated heat-treated steel sheet for a battery can, by using a high frequency glow discharge optical emission spectrometric analyzer, the difference (D2-D1) between the depth (D1) at which the Fe intensity exhibits a first predetermined value and the depth (D2) at which the Ni intensity exhibits a second predetermined value is less than 0.04 μm.
