A light receiving module and a light receiving method to reduce polarization dependence, used in evaluation of polarization characteristics of various optical parts. The light receiving module has an optical mechanism including a first light transmission plate and a second light transmission plate between a first lens and a second lens, and a light receiving element of the outside of the optical mechanism. The first light transmission plate is inclined at such an angle as to have the same value as polarization dependence due to the inclination of the light receiving surface of the light receiving element, and subsequently the first light transmission plate is rotated by 90° in relation to the optical axis.
