Plating electrode and plating method that uses the plating electrode

A plating electrode used for forming a plating film on an object to be plated, the plating electrode comprising:

• a plating-solution-impregnated fabric formed into an annular shape;
• an annular part disposed inside the annular shape of the plating-solution-impregnated fabric, and provided in a state in which an outer surface of the annular part is kept in close contact with an inner surface of the plating-solution-impregnated fabric, the annular part having conductivity;
• a first rotary part provided inside the annular part, electrically connected to the annular part, and configured to be rotatable while ensuring conductivity;
• and
• a second rotary part provided inside the annular part, and configured to rotate in synchronization with driving of a motor,
• an anode of a DC conversion power supply being electrically connected to the first rotary part,
• a cathode of the DC conversion power supply being electrically connected to the object to be plated,
• the annular part being caused to turn in synchronization with rotation of the first rotary part and the second rotary part to cause the plating-solution-impregnated fabric to turn in an annular direction, thereby causing the plating-solution-impregnated fabric to come into contact with and to slide against a portion to be plated of the object to be plated.
