A device of estimating a slip angle of vehicle wheel has an attitude-toward-road surface estimation section that uses a series of distances to measurement points on a road surface to estimate vehicle-body-road-surface coordinate conversion information (VCCI) for conversion from a vehicle-body coordinate system to a road-surface coordinate system, an on-road-surface inertia quantity calculation section that removes a gravity acceleration component from the vehicle-body inertia quantity to obtain inertia quantity caused by motion of a vehicle body and uses the VCCI to convert from the inertia quantity caused by the motion of the vehicle body to the road-surface coordinate system, and a wheel slip angle estimation section that estimates a sideslip angle of the vehicle wheel on the basis of a difference between a wheel acceleration vector and the acceleration vector converted to the road-surface coordinate system.
