发明名称 DUST REMOVING DEVICE AND IMAGING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a dust removing device that can be properly designed and controlled, and has high dust removing performance even in a low-temperature environment; and an imaging device using the dust removing device.SOLUTION: A dust removing device 470 comprises a piezoelectric element 430 including a piezoelectric material 431 and a pair of opposing electrodes, a vibration member 410, and a fixing member that has at least a polymeric compound component; and is installed on a substrate 501. The phase transition temperature T from a first ferroelectric crystal phase to a second ferroelectric crystal phase of the piezoelectric element 431 is set to -60°C≤T≤-5°C so as to properly design and control the dust removing device 470, and obtain high dust removing performance even in a low-temperature environment.
