Provided is a road-surface-detection device capable of detecting not only a road surface in a dry state, a road surface in a wet state, and a road surface in a frozen state, but also the type of a road surface based on a constituent of the road surface. A road-surface-detection device 100 includes: a light source 80 that emits, to a road surface 300, light of a plurality of different wavelengths including at least one type of visible light in visible light to near-infrared wavelength ranges; detectors 81 and 82 that detect reflection intensities of reflected light having a plurality of different wavelengths including at least one visible light in reflected light emitted from the light source 80 and reflected on the road surface 300; and a road surface determiner 70 that determines a type of a road surface based on the reflection intensities of the reflected light having the plurality of different wavelengths and detected by the detectors 81 and 82.
