A damping force control apparatus includes a damping force control means (CC) controlling a damping force of a shock absorber (AB) provided between a sprung mass and an unsprung mass of each wheel (WH) of a vehicle, a detection means (DT) detecting at least an acceleration of the sprung mass in an up-down direction and a relative displacement between the sprung mass and the unsprung mass, a damping coefficient calculation means (CE) calculating a damping coefficient to be applied to the damping force control by the damping force control means (CC) based on detected results of the detection means (DT), a sensed acceleration increment calculation means (WF) calculating a sensed acceleration increment corresponding to an increment of sense according to the Weber Fechner law on the basis of the detected results of the detection means (DT), and a modification means (MD) modifying the damping coefficient in accordance with a sensed acceleration increment calculated by the sensed acceleration increment calculation means (WF).
