PROBLEM TO BE SOLVED: To provide a piezoelectric actuator which has a large deformation amount, and to provide a piezoelectric mirror element and an electronic apparatus which use the piezoelectric actuator.SOLUTION: A piezoelectric actuator includes: a conductive support plate 3; and a piezoelectric element 4 having a plate shape and including an electrode 4c, which is formed by sintered conductive particles, on at least one main surface. The support plate 3 is adhered to a main surface of the piezoelectric element 4, which is located at the side where the electrode 4c is provided, by an adhesive layer 8. A part of the conductive particles (4c-1) penetrates through the adhesive layer 8 and electrically connects the electrode 4c with the support plate 3. |
