Abstract
Provided is a lens-driving unit reduced in size and improved in durability. A first flexible printed wiring board of the lens-driving unit has a terminal on one side connected to a first piezoelectric motor and lead in parallel to an optical axis, and the other side connected to a unit for power supply and control, in a loop shape gently bent to an opposite direction to the leading direction. A second flexible printed wiring board of it has a terminal on one side connected to a piezoelectric motor and lead in parallel to the optical axis, and the other side connected to a unit for power supply and control, in a loop shape gently bent to the opposite direction to the leading direction. At such reference plane a structure symmetrically having the second and the first flexible printed wiring board with respect to a reference plane, is employed.
