Abstract
A method of forming a deposited film according to the present invention includes: introducing a starting gas into a discharge space in a reaction vessel; and applying electric power to generate discharge to decompose the starting gas, wherein, when a self-bias voltage value which is generated at an electrode applied with first electric power reaches a preset threshold, second electric power higher than the first electric power is applied to the electrode to change the self-bias voltage value to another self-bias voltage value larger in absolute value than the threshold, and the deposited film is formed.
