Abstract
Provided is a piezoelectric actuator, a linear driving device, and an electronic device that achieve displacement of a drive shaft of a given magnitude even in a case where a low voltage is applied. A piezoelectric actuator includes a piezoelectric material composed of a stack of plate-shaped piezoelectric elements, the piezoelectric material being expandable and contractable in a direction of a plate surface thereof; an elastic plate having the piezoelectric material formed on a plate surface of the elastic plate, and a drive shaft having one end fixed to either the piezoelectric material or the elastic plate in a direction perpendicular to the plate surface of the piezoelectric material.
