Provided are a reflection film that can display videos in a case of being applied in a head-up display, and that can also compatible with various types of authentication such as face authentication and iris authentication performed with various infrared light sources, a windshield glass, and a head-up display system. The reflection film includes a visible light selective reflection layer and an infrared light selective reflection layer. The visible light selective reflection layer has at least one reflection peak in a range of 380 nm to 850 nm, and has a natural light reflectivity of 5% to 25% at a wavelength of the reflection peak. The infrared light selective reflection layer satisfies requirement 1 or requirement 2.Requirement 1: two or more reflection peaks are provided in a range of 900 nm to 1200 nm, and a natural light reflectivity each of the reflection peaks is 26% or more.Requirement 2: one reflection peak is provided in a range of 900 nm to 1200 nm, a natural light reflectivity of the reflection peak is 26% or more, and a wavelength bandwidth in a region where a reflectivity higher than an average value of a maximum value and a minimum value of a reflectivity is 120 nm to 500 nm.
