Abstract
The variable shape mirror (1) includes a substrate (2) and a bulk piezoelectric body (3). On the piezoelectric body (3), a specular surface (4) is formed, and further a plurality of grooves (5a-5e) are formed at a predetermined interval. The grooves (5a-5e) are arranged so as to surround the specular surface (4) and filled with the conductive members. The conductive members embedded in the grooves (5a-5e) are connected electrically to one of a pair of common electrodes (7a and 7b) that is disposed to cross the grooves (5a-5e) and are formed to be electrodes having different polarities in alternating manner in the direction from the inner side to the outer side of the grooves (5a-5e).
