A method of manufacturing high capacitance anode and cathode films of capacitors is revealed. Perform sputter deposition on a cathode aluminum foil in a vacuum chamber to form a cathode metal layer which is a titanium layer on a surface of the cathode aluminum foil. Then titanium continuously reacts with nitrogen to form cathode columnar crystal deposition on a surface of the cathode metal layer and get a cathode film. Perform sputter deposition on an anode aluminum foil in a vacuum chamber to form an anode metal layer which is a titanium layer on a surface of the anode aluminum foil. Then titanium continuously reacts with oxygen and nitrogen to form anode columnar crystal deposition on a surface of the anode metal layer and get an anode film. Next use the cathode and anode films with high capacitance to form cathode and anode electrodes of the capacitor.
