Abstract
A position testing apparatus includes a stage on which a piezoelectric element object is set, a through hole formed through the stage and covered with the piezoelectric element set on the stage according to a positioning state, and a flow measurement unit configured to draw air through the through hole from around the piezoelectric element and determine the positioning state of the piezoelectric element according to a flow rate of the drawn air. The position testing apparatus is capable of surely testing a positioning state of the piezoelectric element.
