摘要：
A piezoelectric actuator that includes a piezoelectric substrate, first and second electrodes, and a conductive layer. The first and second electrodes are configured to apply a voltage to the piezoelectric substrate. The conductive layer is formed on the first electrode. The conductive layer is made of a metal or an alloy different in color from the second electrode.
