Abstract
Disclosed are an electrodeposition process comprising the steps of transporting a substrate in an electrodeposition bath, and forming a film on the substrate, which process further comprises the step of removing particles from the surface of the substrate; and an electrodeposition apparatus comprising an electrodeposition tank for holding therein an electrodeposition bath, a mechanism for transporting a continuous-length-substrate while holding the substrate thereon, and an opposing electrode, which apparatus further comprises a mechanism for removing particles from the surface of the continuous-length substrate. These can provide a process and an apparatus by and in which dust in the bath or any particles due to film-peeling from electrodes can be prevented from causing difficulties such as impact marks in a film-deposited substrate during its transport, to form a good-quality electrodeposited film.
