Abstract
A titanium foil or a titanium sheet is produced by electrodeposition from molten salt using constant current pulse, the method comprising: forming an electrodeposited titanium film on a surface of a cathode electrode made of glassy carbon, graphite, Mo, and Ni, and separating thereafter the electrodeposited titanium film from the cathode electrode by performing one or both of applying an external force to the electrodeposited titanium film and removing the cathode electrode. This enables the electrodeposited titanium film electrodeposited on the cathode electrode to be peeled from the cathode electrode simply and at low cost.
