To provide an imaging apparatus which employs an optical low pass filter comprising a high polymer made film and a high polymer made double-sided tape, the imaging apparatus which can maintain excellent color reproducibility even when the optical low pass filter is degenerated by an ultraviolet ray.

When an optical low pass filter degeneration detection means detects a degeneration in the optical low pass filter, the imaging apparatus uses a white balance correction means to correct a white balance control means thereby capable of maintaining the excellent color reproducibility even when the optical low pass filter is degenerated.
