Beschreibung
Zusammenfassung:	This dielectric film is a dielectric film comprising an oxide having a perovskite structure. The oxide comprises (1) Bi, Na and Ti, (2) at least one of Ba and Ca, and (3) at least one element Ln selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Yb and Y. When ratios of the numbers of atoms of Bi, Ba and Ca to the total of the numbers of atoms of Bi, Na, Ba and Ca in the oxide are represented by XBi, XBa and XCa, respectively, the ratios satisfy 0.2≤XBi/(XBa+XCa)≤5.
