The present invention achieves a technique that makes it possible to estimate a ground contact load of a vehicle with sufficiently high accuracy. A ground contact load estimation device (100) acquires a wheel angular speed, a steady load, and an inertia load of a vehicle, uses the steady load and the inertia load to cause a first gain calculation section (122) to calculate a first gain, multiplies a variation in wheel angular speed by a second gain so as to cause a tire effective radius variation calculation section (121) to calculate a tire effective radius variation, and multiplies the tire effective radius variation by the first gain so as to estimate a road surface load.
