A film forming apparatus by which property values in a film formed by the AD method can be improved. The film forming apparatus includes: a chamber having a substrate stage for holding a substrate on which a film is to be formed; an aerosol generating unit for generating an aerosol by dispersing a raw material powder into a gas; a magnetic field applying device for applying a magnetic field to a flow path of the aerosol generated by the aerosol generating unit so as to orient crystal orientation in the raw material powder in an aerosol state; and an injection nozzle for spraying the aerosol applied with the magnetic field by the magnetic field applying device to the substrate so as to deposit the raw material powder, in which the crystal orientation is oriented, on the substrate.
