Abstract
Disclosed are a method and an apparatus for forming an oxide coating film with excellent corrosion resistance and adhesiveness on a cathode made of a metal plate by a simple process at low cost. A direct current voltage is applied between an anode () and a cathode () in an electrolyte solution which cathode () is made of a metal plate to be coated with oxide and arranged opposite to the anode (), while supplying oxygen or a gas containing oxygen into the electrolyte solution, so that the metal plate cathode () is coated with oxide, thereby being formed into a oxide-coated metal plate.
