A vehicular internal rearview mirror assembly includes a mirror casing accommodating an internal mirror reflective element having a dielectric mirror reflector that is transmissive to radio waves and reflective to visible light incident thereat. A radar sensor is disposed behind the internal mirror reflective element and includes (i) a plurality of radar transmitting antennas and (ii) a plurality of radar receiving antennas. The dielectric mirror reflector includes a plurality of high refractive layers and a plurality of low refractive layers. Visible light incident at an external surface of the internal mirror reflective element is reflected by the dielectric mirror reflector as visible light having a reflectance spectrum similar to that of a metallic mirrored surface. With the vehicular internal rearview mirror assembly mounted in a vehicle, presence of the radar sensor behind the internal mirror reflective element is rendered covert by the dielectric mirror reflector.
