Abstract
An apparatus for forming a zinc oxide film on a sheet substrate including a tank containing an aqueous electrolytic solution containing at least nitrate ions and zinc ions, conveyer means for continuously feeding and conveying an elongated electroconductive sheet substrate having two major surfaces in a direction while dipping a lengthwise portion of the sheet substrate in the electrolytic solution, a counter electrode immersed in the electrolytic solution so as to be opposite to the lengthwise portion of the sheet substrate, and a power supply disposed so as to pass a current between the sheet substrate and the counter electrode, wherein the conveyer means include a plurality of rollers and an endless belt wound about the rollers so as to have a conveyer surface contacting and covering one of the major surfaces of the lengthwise portion of the sheet substrate dipped in the electrolytic solution while moving together with the sheet substrate.
