A camera module for preventing lens tile by surrounding the width of a spiral wire part is provided to reduce the height of the camera module by horizontally composing a movement spiral wire part and a piezo-electric device. A piezoelectric element assembly(30) includes a piezoelectric element and a spiral wire part. The piezoelectric element has the feature expanding if the electricity is compacted. The lens assembly moves with the rotation move of the spiral wire part according to the spiral wire of the spiral wire part. The lens assembly moves up and down. Right and left edge of the piezoelectric element move the spiral wire part.
