    Abstract: PROBLEM TO BE SOLVED: To provide an electrolytic treatment device which performs an electrolytic treatment such as alkaline electroplating (e.g. zinc plating) or its pretreatment, maximizes the treatment efficiency possible, and increases the productivity of a treated article (e.g. a plated article as a finished article) to reduce its cost.
    SOLUTION: The electrolytic treatment apparatus has an insoluble counter electrode 7 installed in a treatment vessel. The counter electrode 7 has sterically effective current-carrying planes consisting of the sum of front current-carrying planes formed by parts facing a work 8 and side current-carrying planes formed by parts extending from the front current-carrying planes as the starting points in the direction so as to leave the work 8. Thus, the current-carrying area is maximized.
