Abstract:
A process for producing a zinc oxide film comprising the steps of:transporting a conductive long substrate via above at least one electrode comprised of zinc in an electrodeposition bath held in an electrodeposition tank and applying an electric field between the electrode and the conductive long substrate, thereby forming a zinc oxide film on the conductive long substrate, the process comprising: a first step of forming the zinc oxide film on a part of the conductive long substrate; a second step of stopping the application of the electric field and the transportation; a third step of bringing at least a part of the conductive long substrate, which is in contact with the electrodeposition bath in the second step, out of contact with the electrodeposition bath; and a fourth step of re-contacting at least a portion of the part of the conductive long substrate brought out of contact with the electrodeposition bath in said third step with the electrodeposition bath.
