Provided is a lens driving device reduced in sizes. In a right side region divided by a virtual center line vertically passing the outer circumference region of both lens group holding frames, including an optical axis, a lens driving device concentratedly has a first guide pole, a second guide pole, a lead screw of a first piezoelectric motor, and a lead screw of a second piezoelectric motor, when viewed from the front. Furthermore, the lead screw of the first piezoelectric motor and the lead screw of the second piezoelectric motor are arranged in an intermediate region between the first guide pole and the second guide pole.
