<P>PROBLEM TO BE SOLVED: To provide a wavefront aberration correction mirror of a structure which reduces distortion, can realize lower electric power and can enhance the efficiency of a piezoelectric element and an optical pickup. <P>SOLUTION: Thin-film threads (16) are formed on a mirror substrate (6) and conductive projections (15) are electrically connected to the threads (16). The piezoelectric element (2) is bonded to the mirror substrate (6) by an adhesive (18) and at this time, piezoelectric element electrodes (4a) are electrically connected to the conductive projections (15). <P>COPYRIGHT: (C)2004,JPO |
