A rubber member holding an optical low pass filter seals an imaging sensor and the optical low pass filter, and a piezoelectric element vibrates an edge portion of the optical low pass filter in the direction of an optical axis, and gives the optical low pass filter a rotational force around an axis orthogonal to an imaging optical axis.
