<p>[Task] A non-open type barrel is used, even a long bolt class is capable of being plated without problem, further electric resistance is decreased in the plating from a small workpiece to a large workpiece and the amount of CO 2 discharged is capable of being decreased. [Means for Resolution] A barrel apparatus for barrel plating in which a non-open type barrel is used, a workpiece is accommodated in the barrel and is immersed in a plating liquid, a negative electrode that is arranged within the barrel and a positive electrode that is arranged in the plating liquid are electrically connected and electroplating is performed while the barrel is rotated about a center shaft, includes a negative electrode 11 arranged at a position that is in contact with a workpiece W inside the barrel, and a positive electrode 12 is arranged at a position that is not in contact with the workpiece inside the barrel, wherein the barrel has a form that is substantially a cylinder or substantially a polygonal cylinder and a ratio between the diameter and the length thereof is in a range of 1:0.7 to 1:1.</p> |
