摘要： In a piezoelectric device, a first electrode and a second electrode are disposed to be opposed to each other on plate surfaces of the piezoelectric device, a first electrode plane of the piezoelectric device is fixedly bonded to a plate surface of a vibrating plate, a piezoelectric material forming the piezoelectric device is polarized in a direction parallel to the first electrode plane, the piezoelectric device is fixed to a base through a second electrode plane of the piezoelectric device, and the piezoelectric device generates a thickness-shear vibration with the fixed second electrode plane being a reference plane. The piezoelectric vibration generated by the piezoelectric device generates a flexural vibration in the vibrating plate, to thereby remove dust adhering to a surface of the vibrating plate.
