Abstract
The variable-shape mirror is provided with a support base and a minor portion that is disposed to face the support base and that has on a side thereof facing away from the support base a minor surface which is irradiated with a light beam. There are also provided piezoelectric elements that are sandwiched between the support base and the mirror portion and that vary the shape of the mirror surface. The piezoelectric elements are bonded, through a thin layer of metal that is separately provided for bonding, to at least one of the support base and the mirror portion. A driving voltage to the piezoelectric elements is supplied through the thin layer of metal.
