A scanner comprises a mirror, a first and second springs, an insulation layer and a first and second piezoelectric elements. The insulation layer is directly attached to the mirror and the first and second springs. The first and second piezoelectric elements are directly attached to the insulation layer. The first piezoelectric element has a first portion above the first spring, a mid-range portion above the mirror and a second portion above the second spring. The second piezoelectric element has a first portion above the first spring, a mid-range portion above the mirror and a second portion above the second spring. The first piezoelectric element has a first upper electrode layer, a first piezoelectric layer and a first lower electrode layer. The second piezoelectric element has a second upper electrode layer, a second piezoelectric layer and a second lower electrode layer. The first upper electrode layer of the first piezoelectric element and the second lower electrode layer of the second piezoelectric element are electrically connected to a first electrode. The first lower electrode layer of the first piezoelectric element and the second upper electrode layer of the second piezoelectric element are electrically connected to a second electrode.
