ABSTRACT:
In a variable-shape mirror (1) of which the shape of the mirror surface can be varied, four piezoelectric elements (4) are sandwiched between a support base (2) and a mirror portion (3), and are arranged symmetrically in cross-shaped directions. The piezoelectric elements (4) are bonded to the mirror portion (3), and serve both to vary the shape of the mirror portion (3) by being driven and to fix the mirror portion (3) to the support base (2). Support portions (5) are arranged one inside each of the piezoelectric elements (4). With this structure, a small movement that the piezoelectric elements (4) produce when driven can be converted into a large movement of the mirror portion (3).
