To provide a near field rotatory polarization measuring instrument having a spatial resolution of light diffraction limit or more.
This near field rotatory polarization measuring instrument 10 is provided with: a near field probe 14 having in its tip an opening smaller than a wavelength of light used in measurement, and for emitting a near field light of linear polarization from the opening to irradiate a sample with the near field light; a detecting means 22 for detecting the light transmitted through the sample; an analyzer 18 provided in a preceding stage of the detecting means; and an analyzer rotating means 20 for rotating the analyzer around an optical axis as the center, and for changing an angle of a transmission axis thereof, and measures an angle of rotation of the sample by rotating the analyzer with the analyzer rotating means.
