    摘要: A thin film piezoelectric actuator comprises a driving part at least one end of which is supported by an anchor portion. The driving part includes: a piezoelectric film, a first lower electrode provided under a first region of the piezoelectric film, a second lower electrode provided under a second region different from the first region of the piezoelectric film, a first upper electrode provided opposite to the first lower electrode on the piezoelectric film, a second upper electrode provided opposite to the second lower electrode on the piezoelectric film, a first connection part that electrically connects the first lower electrode and the second upper electrode via a first via hole formed in the piezoelectric film, and a second connection part that electrically connects the second lower electrode and the first upper electrode via a second via hole formed in the piezoelectric film.
