A road surface information collection device that consumes less power than conventional counterparts is provided. The road surface information collection device 10 according to the present disclosure samples the acceleration applied to an acceleration sensor 13 with a first sampling cycle S1, and a second sampling cycle S2 that is shorter than that. A rotational position of the acceleration sensor 13 is computed based on changes in first sampling data obtained by the sampling performed with the first sampling cycle S1, and detection results of the acceleration sensor 13 are sampled with the second sampling cycle S2 based on a condition that the acceleration sensor 13 is positioned within a first predetermined range L1 including a back side of a point on a tire 92 in contact with a ground to obtain second sampling data.
