    摘要： The present invention aims to provide an anode for electroplating that can be relatively easily manufactured without the need for ancillary facilities or anolyte management, and without requiring expensive or special metals.
    The present invention relates to an anode for electroplating, comprising:
    an input part where power is input from a power source;
    a pair of support parts that extend in a first direction, are arranged at intervals in a second direction intersecting the first direction, receive power supply from the input part, and whose portions in contact with a plating solution are covered with an insulating material; and
    an electrification part that extends in the second direction, one end of which is connected to one of the pair of support parts, the other end of which is connected to the other of the pair of support parts, and receives power supply from the pair of support parts,
    wherein the electrification part includes several current paths arranged at intervals in the first direction, and
    a cross-sectional area of the electrification part is smaller than that of each of the support parts.

    摘要： An object of the present invention is to provide a method and system of electroplating using an anode that can be prepared relatively easily without the need for ancillary equipment or anolyte management, and without the need for expensive metals or special metals.
    The present invention relates to a method of electroplating an article with metal, the method comprising the steps of:
    allowing a current to flow in a plating bath containing ions of the metal and an organic compound additive, wherein
    the plating bath comprises the article as a cathode and a conductive base material as an anode,
    a part of a surface of the conductive base material is covered with an insulating material, and a remaining part is exposed, and
    a current flowing portion is dispersedly present in the anode.
