This device for detecting a road surface state includes: a stereo camera including a plurality of cameras that each image a road surface in front of a vehicle and are arranged such that a parallax is vertically generated; and an arithmetic processing circuit that vertically searches for corresponding points of a plurality of images taken by the plurality of cameras of the stereo camera, to thereby calculate a parallax, and calculates a height of the road surface as a state of the road surface on a basis of the calculated parallax.
