    Abstract: A film forming apparatus according to the present invention comprises: a processing chamber; a substrate holder for holding a substrate within the processing chamber; a target electrode, disposed above the substrate holder, for holding a metal target and supplying electrical power from a power source to the target; an oxidizing gas introduction mechanism for supplying an oxidizing gas to the substrate; and a gas supply unit for supplying an inert gas to the space where the target is disposed. Constituent metal is discharged from the target in the form of sputter particles, whereby a metal film is deposited on the substrate, and the metal film is oxidized by the oxidizing gas introduced by the oxidizing gas introduction mechanism, thereby forming a metal oxide film. When the oxidizing gas is introduced, the gas supply unit supplies the inert gas to the space where the target is disposed so that the pressure therein is positive with respect to the pressure in a processing space.
