A hydraulic control device in which a supply path for supplying oil to a control object and/or a discharge path for discharging oil from the control object is provided with a control valve, the electric current of which is controlled on the basis of the deviation of the actual oil pressure of the control object from the target oil pressure for the control object and which supplies oil to the control object or discharges oil from the control object in an amount corresponding to the electric current. The device is configured so that the oil volume necessary for matching the actual oil pressure to the target oil pressure is determined on the basis of the deviation and the electric current corresponding to the necessary oil volume is determined on the basis of the relationship between the control valve electric current and the flow rate.
