A ferroelectric capacitor includes a lower electrode, a ferroelectric film provided over the lower electrode and having a perovskite-type structure and an upper electrode provided over the ferroelectric film. The ferroelectric film includes a first ferroelectric film part having a first crystal system and formed along at least one interface with at least one of the lower electrode and the upper electrode and a second ferroelectric film part having a second crystal system that is different from the first crystal system.
