摘要： The present invention provides a film formation method capable of forming a favorable amorphous carbon film under a low vacuum by using a bipolar-type PBII apparatus and the amorphous carbon film to be produced by the film formation method. The film formation method is carried out to form the amorphous carbon film under a low vacuum (1000 to 30000 Pa) by using a power source for the bipolar-type PBII apparatus. There are provided inside a chamber (1) a power source side electrode (3) connected to a power source (6) for the PBII apparatus and a grounding side electrode (4) opposed to the power source side electrode (3). A base material (2) is disposed on one of the power source side electrode (3) and the grounding side electrode (4). Plasma of a noble gas and that of a hydrocarbon-based gas are generated between the base material (2) and the electrode where the base material (2) is not disposed to form the amorphous carbon film on a surface of the base material (2).
