Abstract
In order to solve various problems such as a reduction in a paint resin with the progress of electrodeposition coating treatment and remelting of a coating film or the occurrence of pinholes caused by an increased concentration of an electrolyte as a result of the reduction, upsizing of a hollow electrode with a membrane for electrodeposition coating combined with a barrier membrane (e.g., an ion exchange membrane) and an increase in the number of components should be avoided. In order to realize this, a barrier membrane 20 such as an ion exchange membrane is attached to the exterior surface of an electrode main body 10, which is in a hollow state made of a conductive material and configured so as to allow a liquid to pass through freely between the inside and outside of the electrode serving as a support.
