Abstract
A conducting roller is used in an electroplating apparatus, and includes a conductive roller body, which has two diameter-reduced end portions that are journalled within two stationary conductive sleeve units. A conductive liquid is filled within two sealed gaps between the end portions of the roller body and the sleeve units, thereby transmitting cathode current from the conductive sleeve units to the end portions of the roller body.
