전지캔용 니켈 도금 열처리 강판(1)으로서, 강판(11) 상에 4.4~26.7g/㎡의 니켈층을 가지고, 고주파 글로우 방전 발광 분광 분석 장치에 의해 상기 전지캔용 니켈 도금 열처리 강판의 표면으로부터 깊이 방향을 향해 Fe 강도 및 Ni 강도를 연속적으로 측정했을 때, Fe 강도가 제1 소정값을 나타내는 깊이(D1)와 Ni 강도가 제2 소정값을 나타내는 깊이(D2)의 차분(D2-D1)이 0.04μm 미만인 것을 특징으로 하는 전지캔용 니켈 도금 열처리 강판(1)을 제공한다. The present invention provides a nickel-plated heat-treated steel sheet for a battery can (1), having a nickel layer with a nickel amount of 4.4 to 26.7 g/m 2 on a steel sheet (11), 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.
