Definitions

  • the small mass-shaped electric nickel for example, can be manufactured by using a cathode plate on which a plurality of circular conductive sections are arranged at regular intervals, by precipitating nickel on the conductive section with electrolysis, and then, by peeling off electrodeposited nickel from the conductive section. According to such a method, it is possible to effectively manufacture a plurality of small mass-shaped electric nickels from one cathode plate.
  • the present invention has been made in consideration of such circumstances of the related art, an object thereof is to provide a cathode plate for metal electrodeposition in which a non-conductive film on a metal plate is less likely to be lost, and thus, can be repeatedly used, and even in a case where the non-conductive film is lost, maintenance becomes easy, and a manufacturing method for the same.
  • the non-conductive film 3 is not particularly limited insofar as the non-conductive film has non-conductivity, and is formed of a material that is less corrosive with respect to an electrolysis solution to be used.
  • the non-conductive film 3 is configured of a thermosetting resin or a photocurable resin (an ultraviolet curable resin or the like), from the viewpoint of easy film formation.
  • an insulating resin such as an epoxy-based resin, a phenolic resin, a polyamide-based resin, a polyimide-based resin is exemplified.
  • the cathode plate 1 was prepared as with Example 1, except that the height L1 of the protrusion 2a of the metal plate 2 was 40 ⁇ m.
  • the height L2 of the substantially vertical section 2d was measured by the laser displacement meter, and thus, was 30 ⁇ m on average
  • the height L3 of the inclined section 2e was 10 ⁇ m on average
  • the length L4 of the inclined section 2e was 50 ⁇ m on average.
