Abstract
A variable-shape mirror is provided with: a support base; a mirror portion that is disposed to face the support base and that has, on a side thereof facing away from the support base, a mirror surface which is irradiated with a light beam; fixed portions that fix the mirror portion to the support base; and piezoelectric elements that are sandwiched between the support base and the mirror portion and that vary a shape of the mirror surface. Here, the piezoelectric elements are arranged closer to a center of the mirror portion than the fixed portions are.
