PROBLEM TO BE SOLVED: To provide a negative electrode which contributes to space saving and electrolytic efficiency improvement of an electrolytic device.SOLUTION: A negative electrode for an electrolytic device is a negative electrode to be used for an electrolytic device which precipitates metal to the negative electrode from a metal-containing solution by an electrolytic method including a negative electrode and a positive electrode opposed to each other. The negative electrode is constituted of two or more negative electrode plates electrically connected in parallel, the negative electrode plates electrically connected in parallel are arranged in parallel at an interval, and in two or more negative electrode plates, the negative electrode plates of equal to or more than (the number of total electrode plates-1) have a plurality of through holes.SELECTED DRAWING: Figure 1 【課題】本発明の目的は電解装置の省スペース化と電解効率向上に寄与する陰極を提供すること。【解決手段】本発明の電解装置用陰極は、対向する陰極と陽極とを備えた電気分解法によって金属含有溶液から金属を陰極に析出させる電解装置に用いる陰極であって、前記陰極は電気的に並列に接続された２枚以上の陰極板で構成されていると共に、前記電気的に並列に接続された陰極板は互いに間隔を有して並列に配置されており、且つ、前記２枚以上の陰極板のうち、［全陰極板数−１］枚以上の陰極板は複数の貫通孔を有する。【選択図】図１
