[Problem] Provided is a nickel-plated steel sheet in which a plating layer has adhesiveness to a substrate, which has adhesiveness to other members, and the total thickness of which, including the thickness of a roughened layer, is reduced. [Solution] A nickel-plated steel sheet according to the present invention comprises a substrate which is constituted by a steel plate, a roughened nickel layer which is provided on the substrate, and an iron-nickel alloy layer which is provided between the substrate and the roughened nickel layer. Le problème décrit par la présente invention est de fournir une tôle d'acier plaquée de nickel dans laquelle une couche de placage présente une adhésivité à un substrat, lequel présente une adhésivité à d'autres éléments, et dont l'épaisseur totale, y compris l'épaisseur d'une couche rugosifiée, est réduite. La solution consiste en une tôle d'acier plaquée de nickel selon la présente invention comprenant un substrat qui est constitué d'une plaque d'acier, d'une couche de nickel rugosifiée qui est disposée sur le substrat, et d'une couche d'alliage fer-nickel qui est disposée entre le substrat et la couche de nickel rugosifiée. 【課題】基材に対するめっき層の密着性と他の部材に対する密着性を備えつつ、粗化層まで含めた合計厚みを薄くしたニッケルめっき鋼板を提供する。 【解決手段】鋼板からなる基材と、前記基材上に設けられる粗化ニッケル層と、前記基材及び前記粗化ニッケル層との間に設けられる鉄ニッケル合金層と、を有するニッケルめっき鋼板。
