Abstract
A piezoelectric element feeder for feeding a piezoelectric element, includes a drawing unit that draws a first electrode surface of the piezoelectric element with use of negative pressure and transfers the piezoelectric element onto the actuator attaching part and a probe movably supported with the drawing unit and used to measure electric characteristics of the piezoelectric element. A front end of the probe is brought into contact with the first electrode surface when or just before the drawing unit draws the first electrode surface, to enable a measurement of the electric characteristics of the piezoelectric element.
