    摘要: Provided are: a cathode plate for metal electrodeposition which makes it less likely to lose a non-conductive film on a metal plate, which can be used repeatedly, and for which maintenance is easy even if a non-conductive film is lost; and a manufacturing method for such cathode plate. This cathode plate 1 includes a metal plate 2 on which a plurality of disk-shaped protrusions 2a are arranged, and a non-conductive film 3 formed in flat sections 2b which are sections of the metal plate 2 other than the protrusions 2a. The protrusions 2a each have a side face that has a shape formed of a substantially vertical section 2d and an inclined section 2e. A height L1 of each protrusion 2a is 50µm to 1000µm, and when an intersection of the side face of the protrusion and a vertical line that is vertically lowered from a position X that is 20µm outward from the outer peripheral edge of the protrusion is defined as Y, then a length L2 from X to Y is at least 40µm but not more than 0.8×L1µm.
