Abstract:
1. A plasma CVD apparatus for depositing a coating on a surface of a sheet shape continuous substrate, comprising: a vacuum chamber; a pair of deposition rollers disposed in said vacuum chamber and connected to both poles of an AC power supply, the deposition rollers around which the substrate is wound; a gas supplying device for supplying a gas containing a source gas to a deposition zone serving as one part of or all of a region on one side of a line connecting rotation centers of said pair of deposition rollers; and a magnetic field generating device provided at a location relative to each of said deposition rollers to generate magnetic fields in which plasma of the source gas is generated in a predetermined region including surfaces of the deposition rollers in the deposition zone by applying an AC voltage to each of said deposition rollers from the AC power supply, wherein said magnetic field generating device causes the source gas in regions adjacent to surfaces of parts of said pair of deposition rollers positioned in the deposition zone to become the plasma so as to form plasma regions, and the substrate is wound around said pair of deposition rollers so as to pass through the plasma regions.
