1. An image pickup device-equipped rear-view mirror, comprising: a mirror element, comprising a dielectric multilayer reflecting film formed on a rear surface of a substrate, the reflecting film consisting of three or four laminated layers, including at least one high refractive index material film layer and at least one low refractive index material film layer; a dark color mask member arranged behind the mirror element such that the rear surface of the substrate faces the dark color mask member; and a near-infrared camera arranged behind the dark color mask member, an optical axis of the near-infrared camera being directed to a surface of the mirror element via the dark color mask member, wherein: the mirror element has an integrating sphere reflectance of 40% to 60% in a visible wavelength range, and a near-infrared transmittance of no less than 70% in a near-infrared wavelength range within a sensitive wavelength range of the near-infrared camera; a near-infrared transmittance of at least a region of the dark color mask member where the near-infrared camera is arranged is no less than 70% in a near-infrared wavelength range within a sensitive wavelength range of the near-infrared camera; and the near-infrared wavelength range in which the mirror element has a near-infrared transmittance of no less than 70% overlaps with the near-infrared wavelength range in which the near-infrared transmittance of the region of the dark color mask member is no less than 70%.
