PROBLEM TO BE SOLVED: To provide a color separator and imaging apparatus, in which the need for a color separating plate is eliminated, a polarization converting section and a diffracting section can be arranged along the same axis on the optical path of the imaging apparatus of an optical system, and a reduction in outer shape is achieved. SOLUTION: The color separator includes the polarization converting section 16 for converting an incoming light ray into a linearly polarized light ray such that the polarization direction of the linearly polarized light ray is selectable from a number of predetermined azimuths, and the diffracting section 6, which is arranged so as to receive the linearly polarized light ray that has gone out of the polarization converting section 16 and which produces a zero-order light ray in which one of multiple different wavelength components is selectively weakened according to azimuth of the polarization direction at least.
