The polarization filter includes a circularly polarized light-separating layer having a cholesteric liquid crystalline phase fixed therein, in which the circularly polarized light-separating layer is a layer which selectively transmits one of the left-hand circularly polarized light and the right-hand circularly polarized light in the specific wavelength band, a λ/4 phase difference layer for light in the specific wavelength band is disposed on one of the surfaces of the circularly polarized light-separating layer, and the λ/4 phase difference layer includes a first phase difference region and a second phase difference region of which slow axis directions are orthogonal to each other. The sensor system includes the polarization filter, a light source which emits light having a wavelength in the specific wavelength band, and a light-receiving element which can detect light having a wavelength in the specific wavelength band. The polarization filter of the present invention can improve the sensitivity of a sensor system using polarized light, and the sensor system of the present invention has high sensitivity and is extremely cost effective.
