摘要：
To provide a PBNZT ferroelectric film capable of preventing sufficiently oxygen ion deficiency. The PBNZT ferroelectric film according to an embodiment of the present invention is a ferroelectric film including a perovskite-structured ferroelectric substance represented by ABO3, wherein the perovskite-structured ferroelectric substance is a PZT-based ferroelectric substance containing Pb2+ as A-site ions and containing Zr4+ and Ti4+ as B-site ions, and the A-site contains Bi3+ as A-site compensation ions and the B-site contains Nb5+ as B-site compensation ions.
