A method for depositing a film comprising a first step for placing an object (10) on which a film is deposited in a reaction chamber (4), a second step for supplying a reactive gas into a reaction chamber (4), and a third step for applying a pulse-like DC voltage between a first conductor (3) and a second conductor (40) arranged in the reaction chamber (4) while being spaced apart from each other. A device for implementing that method is also provided. In the third step, potential difference between the first conductor (3) and the second conductor (40) is preferably set in the range of 50V-3000V, and the pulse frequency of the pulse-like DC voltage applied to the first and second conductors (3, 40) is set at 300 KHz or below. The duty ratio of pulse in the pulse-like DC voltage is set between 20% and 90%, for example.
