Abstract
Provided are a piezoelectric driving device, an optical member driving device, a camera device, and an electronic apparatus, which are capable of performing driving only by one-direction oscillation modes, and capable of combining the oscillation modes to enable driving in two directions. A piezoelectric driving device () includes: a driving portion () to be brought into frictional contact with an object to be driven; and two piezoelectric portions () (), which are provided to the driving portion (), are arranged on a plane with the driving portion () being sandwiched between the two piezoelectric portions, and are configured to be bent with respect to the plane when voltages are applied thereto. Further, a piezoelectric driving device () includes: a driving portion () to be brought into frictional contact with an object to be driven; and at least four piezoelectric portions (to), which are fixed to the driving portion (), are arranged in a circulated manner on a plane and around the driving portion (), and are configured to be bent with respect to the plane when voltages are applied thereto.
