    • PROBLEM TO BE SOLVED: To reduce the consumption rate of an insulating tube to elongate the service life of the insulating tube. SOLUTION: A deposition apparatus includes a plasma gun including a hollow cathode which generates a plasma beam into a vacuum chamber including an exhaust system and one or more intermediate electrodes to provide a potential gradient for the plasma beam, a focusing coil which is provided to surround the outer surface of a tube portion of the vacuum chamber located coaxially with the exit portion for outputting the plasma beam from the plasma gun and draws the plasma beam into the vacuum chamber through the tube portion, and a reflected electron feedback electrode which is placed inside the tube portion coaxially with the exit portion of the plasma gun and has a positive polarity. An insulating tube provided on an inner surface portion of the reflected electron feedback electrode which is grounded and has a potential higher than a potential of the hollow cathode is in electrical contact with the intermediate electrode placed closest to the reflected electrode feedback electrode.

    • PROBLEM TO BE SOLVED: To provide a sheet-like plasma generator capable of extending a film deposition area, and more uniforming a film thickness distribution, and to provide a film deposition apparatus using the sheet-like plasma generator. SOLUTION: In the sheet-like plasma generator, which plasma beams drawn from a plasma gun by a convergence coil are deformed into a sheet shape by being passed through the magnetic field formed by a sheet magnet consisting of a pair of permanent magnets extending in the direction orthogonal to the advancing direction of the plasma beams and arranged opposite and parallel to each other, the sheet magnet includes at least one sheet magnet in which the intensity of repulsive magnetic field at a part corresponding to the center side of the plasma beams is higher than that in a part corresponding to an outer edge side of the plasma beams.
