The electroplating method for a fastener chain having a string of metal elements comprises: a first electroplating step executed on the surface of the metal elements exposed on one primary surface side of the fastener chain; and a second electroplating step executed on the surface of the metal elements exposed on the other primary surface side of the fastener chain. The supply of electricity to the fastener chain in the second electroplating step is initiated within 30 seconds after the surface of the metal elements first contacts a plating liquid during the first electroplating step.
