An optical member driving device is provided that includes a fixed portion with an accommodation space for a lens device, and a movable portion, which has a holding portion for holding an image sensor, and is rockably supported at a position on a rear side of the lens device. The movable portion includes an FPC having a main body portion connected to the image sensor and a connecting portion for connecting the main body portion and an external device and a coil substrate which is fixed on a front surface of the main body portion of the FPC and on which a coil is formed. The connecting portion has a base end portion which rises from a predetermined position on an edge of the main body portion to a front side. The base end portion is opposed to a side surface of the coil substrate with an adhesive interposed.

Optical member driving device with improved optical image stabilizer function

A piezoelectric driving device includes: a driving portion to be brought into frictional contact with an object to be driven, which is moved with respect to a fixed body; and at least two piezoelectric portions, which are formed integrally with the driving portion, are arranged on a predetermined plane with the driving portion being sandwiched between the at least two piezoelectric portions, and are configured to be bent with respect to the predetermined plane when voltages are applied to the at least two piezoelectric portions, wherein outer edges of entirety of the at least two piezoelectric portions are fixed to the fixed body.

Piezoelectric driving device, optical member driving device, camera device, and electronic apparatus

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.
