A CVD system in which a vacuum container is separated into a plasma generating space and a film forming space by a conductive partition wall having plural penetration holes, radicals generated in the plasma generating space are introduced into the film forming space only through the penetration holes of the partition wall, and material gas supplied from outside into the partition wall is introduced into the film forming space through the internal space of the partition wall, which is communicating with the film forming space through plural diffusion holes while separated from the plasma generating space and the penetration holes, and a film is formed on the substrate by the radicals and material gas introduced into the film forming space. In the CVD system, the penetration holes (25) of the conductive partition wall (14) are formed so that the hole diameter at the film forming space (16) side may be equal to or larger than the hole diameter at the plasma generating space (15) side. Besides, the penetration holes (25) are formed of structures (30) independent from the conductive partition wall (14).
