A piezoelectric mirror device (11) comprises a frame portion (12) having a centrally located opening (13), a mirror portion (14) positioned at the opening (13), a pair of mirror support portions (15) adapted to support the mirror portion (14) rotatably relative the frame portion (12) and a pair of drive portions (16) that is a multilayer structure of lower electrodes (17), piezoelectric element (18) and an upper electrode (19). The mirror support portions (15) are formed of a material having a Young's modulus of up to 160 GPa, and the frame portion (12) includes a cutout (13a) at a part of a site wherein there are the drive portions (16) positioned. The cutout (13a) is in contact with the opening (13).
