| Summary: | A piezoelectric actuator includes a supporting substrate, a main body having a first piezoelectric laminate, a second piezoelectric laminate, and a displacement portion, and a first elastic layer. The first elastic layer is fixed to the main body so as to connect a lower surface of the first piezoelectric laminate, a lower surface of the second piezoelectric laminate, a side surface of the first piezoelectric laminate, and a side surface of the second piezoelectric laminate. A first region to fourth region of the first elastic layer is fixed to the principal surface of the supporting substrate by a first to fourth bonding portions. A non-bonding surface is not fixed to the principal surface of the supporting substrate. |
