Provided is a dust removing device that can be designed and controlled appropriately and has high dust removal performance even at low temperature, and an imaging device using the dust removing device. In a dust removing device to be set on a base, including a piezoelectric element formed of a piezoelectric material and a pair of opposing electrodes, a vibration member, and a fixation member containing at least a high molecular compound component, a phase transition temperature T from a first ferroelectric crystal phase to a second ferroelectric crystal phase of the piezoelectric material is set to -60°C<=T<=-5°C, and whereby, the dust removing device can be designed and controlled appropriately and high dust removal performance can be obtained even at low temperature. |
