Disclosed is a plasma chemical vapor deposition apparatus for forming an amorphous thin film, a microcrystalline thin film or a polycrystalline thin film on a surface of a target substrate by utilizing a glow discharge generated by an electric power supplied from a power source, comprising a reaction vessel, means for supplying a reactant gas into the reaction vessel, discharge means for discharge a waste gas of the reactant gas out of the reaction vessel, a ladder-shaped electrode for discharge generation arranged within the reaction vessel, a power source for supplying a high frequency power of 30 MHz to 200 MHz to the ladder-shaped electrode for a glow discharge generation, a heater for heating and supporting a target substrate, the heater being arranged within the reaction vessel in parallel to the ladder-shaped electrode for discharge generation, and a power distributor for uniformly distributing a high frequency power to the ladder-shaped electrode for discharge generation through a power supply wire.
