Abstract
A piezoelectric actuator includes a body portion including a layered piezoelectric element layered in a Y-axis direction of an orthogonal coordinate system XYZ, the body portion extending along a Z-axis direction. The body portion includes a first piezoelectric element that displaces a tip portion in an X-axis direction, a second piezoelectric element that displaces the tip portion in the Y-axis direction, and a third piezoelectric element that displaces the tip portion in the Z-axis direction.
