Patent ID: 7753538

Claim:
A method for fabricating a variable-shape mirror including 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, and piezoelectric elements that are sandwiched between the support base and the mirror portion and that vary a shape of the mirror surface, the method comprising: a step of disposing fixed portions closer to an outer edge of the mirror portion than said each of the corresponding piezoelectric elements, so as to be sandwiched between the support base and the mirror portion; a step of forming electrodes for providing a driving voltage to the piezoelectric elements by separately providing a first and a second thin layers of metal at both end portions of the piezoelectric elements; a step of forming third thin layers of metal on first projections provided on a side of the mirror portion facing the support base; a step of forming a fourth thin layer of metal on a second projection provided on the support base; and a step of bonding the piezoelectric elements and the support base, and the piezoelectric elements and the minor portion by applying heat and pressure to the first and the third thin layers of metal, and the second and the fourth thin layers of metal, respectively.
