Abstract:
1. A plating method comprising: continuously electroplating a surface of a film having a surface resistivity of from 1 to 1,000Ω/□ in a plurality of times in plural plating tanks, wherein the plurality of times are equally divided into a former half stage and a latter half stage, wherein an average plating voltage at the latter half stage of the electroplating step is 60% or less of an average plating voltage at the former half stage of the electroplating, wherein an applied voltage is from 1V to 100V, wherein a current at inlet side of a first plating tank included in the plural plating tanks is from 1 A to 30 A, and wherein a conveying speed of the film is from 1 m/min to 30 m/min.
