A plasma CVD apparatus efficiently coats the surfaces of fine particles with a thin film or super-fine particles by concentrating a plasma near the fine particles. The plasma CVD apparatus includes a chamber, a container disposed in the chamber for housing the fine particles, the container having a polygonal inner shape in a cross section substantially perpendicular to a longitudinal axis of the container, a ground shielding member for shielding a surface of the container other than a housing face, a rotation mechanism for causing the container to rotate or act as a pendulum on an axis of rotation substantially perpendicular to the cross section, an opposed electrode disposed in the container so as to face the housing face, a plasma power source electrically connected to the container, a gas introducing mechanism for introducing a raw gas into the container, and an evacuation mechanism for evacuating the chamber.
