PROBLEM TO BE SOLVED: To feed a sufficient plating liquid into a barrel vessel even if the wall face of the barrel vessel is the one through which the plating liquid is hard to pass, and to prevent the retaining of a superfine object to be plated inside the barrel vessel on a barrel plating device for electroplating. SOLUTION: A plating liquid in a plating bath is pumped up to a plating liquid vessel 13 in the upper direction with a pump 14. The plating liquid is fed into a barrel vessel 8 from the shaft edge side with a feed tube 15. Thus, even if the wall face of the barrel vessel 8 is formed of an extremely fine mesh member 8a for the superfine object to be plated, and the plating liquid is hard to pass therethrough, the plating liquid in a sufficient amount is fed into the barrel vessel 8, and plating can efficiently be applied to the superfine object to be plated.
