Patent ID: 7565880

Claim:
A plasma CVD apparatus comprising an anode electrode and a cathode electrode, which is for forming a thin film on a substrate by performing plasma discharge between the anode electrode and the cathode electrode, comprising: a substrate holder disposed between the anode electrode and the cathode electrode; and one conductive member disposed between the substrate holder and one electrode of either the anode electrode or the cathode electrode, wherein the substrate holder supports the substrate, the one conductive member is provided between the one electrode and the substrate holder so as to substantially cover an entire space between the one electrode and the substrate holder, the one conductive member is electrically connected to the one electrode and the substrate holder; and the conductive member includes: a support plate, each end portion of which is attached to each end portion on both sides of the one electrode such that the conductive member is positioned parallel to the electrically connected one electrode with a space in between; and a plurality of conductive plates or brush-like conductive portions provided for each surface of the support plate facing each of the one electrode and the substrate holder, and the each conductive plate or the each conductive portion is in contact with the one electrode and the substrate holder.
