Abstract
In an electroplating container in which at least one portion of an inside surface of the container is formed from a metal material serving as cathode or anode and an anode or cathode is placed in the container, a composite electroplating liquid containing metal ions and fine solid particles is introduced into a bottom portion of the container in such a manner that the introduced composite electroplating liquid spouts downward against an inside bottom surface of the container and is allowed to flow upward through a flow path formed between the anode and the cathode, and an electric current is applied between the anode and cathode so as to form a composite electroplating layer including the fine solid particles evenly distributed in a metal matrix on a surface of the cathode or anode facing the flow path.
