This specification discloses a plate-like polarizing element for converting light into polarized light having a plurality of units arranged along a common plane across the light, each of the units being provided with dividing means for dividing the light into reflected light and transmitted light whose planes of polarization are orthogonal to each other, varying means for varying the polarized state of at least one of the reflected light and the transmitted light to thereby make the planes of polarization of the two lights coincident with each other, and reflecting means for reflecting one of the reflected light and the transmitted light and directing it substantially in the same direction as the direction of travel of the other. The specification also discloses a polarizing conversion unit provided with such plate-like polarizing element, and a projector provided with such unit.
