  "textContent": "The present invention is intended to provide an image pickup device-equipped rear-view mirror with improved image pickup performance, glare prevention and appearance (design) in addition to improved performance as a vehicle mirror. A mirror element 14 is formed by forming a reflecting film 26 consisting of high refractive index material films 28 and a low refractive index material film 30 on a back surface of a transparent glass substrate 24. The integrating sphere reflectance of the mirror element 14 in the visible range is 40% to 60% and the near-infrared transmittance is no less than 70% for the whole or part of the band belonging to the near-infrared range within the entire sensitive wavelength range of the near-infrared camera 16. A black mask member 18 is attached to an entire back surface of the reflecting film 26. The near-infrared camera 16 is arranged behind the black mask member 18. The region corresponding to the area for image-pickup by the near-infrared camera 16 within the entire region of the black mask member 18 is formed of a visible-light absorption and near-infrared transmission filter 18a. The near-infrared transmittance of the visible-light absorption and near-infrared transmission filter 18a is no less than 70% for the whole or part of the band belonging to the near-infrared range within the entire sensitive wavelength range of the near-infrared camera 16.",
