摘要

The purpose of the present invention is to provide an angular velocity sensor capable of measuring an exact angular velocity, an ink jet head capable of producing an exact amount of ink, and a piezoelectric generating element capable of generating electric power due to positive piezoelectric effect. In the present invention, a piezoelectric film comprising a first electrode, a piezoelectric layer, and a second electrode is used. The first electrode comprises an electrode layer having a (001) orientation. The piezoelectric layer comprises a (NaxBiy)TiO0.5x+1.5y+2-BaTiO3 layer (0.30@x@0.46 and 0.51@y@0.62) having a (001) orientation.
