The piezoelectric actuator includes a first piezoelectric plate, a first electrode, a second piezoelectric plate, a second electrode, and a conductive member. The first piezoelectric plate includes a first surface. The first electrode is disposed on the first surface, and includes a first extending portion. The second piezoelectric plate includes a second surface. The second electrode is disposed on the second surface, and includes a second extending portion. The conductive member includes a first conductive portion and a second conductive portion. The first conductive portion is disposed on the first surface. The second conductive portion is disposed on the second surface. The conductive portion covers, in a first direction, a spacing that is located between the first extending portion and the second extending portion in a second direction.
