PROBLEM TO BE SOLVED: To provide a control device capable of properly controlling oil pressure applied to a pulley irrespective of a change in a pressurized volume caused by a shift change. SOLUTION: The control device for the belt type continuously variable transmission, equipped with a pulley capable of changing a groove width wounded with a belt where an oil pressure is applied so that the belt is pinched with the pulley, and where a hydraulic chamber in which capacity is changed based on a variation in the groove width is provided, and controls an oil pressure in the hydraulic chamber according to a deviation between a target oil pressure and an actual oil pressure, comprises pressurized volume change detectors (steps S102 and S202) for detecting a change in the volume of the hydraulic chamber and an oil pressure control content changers (steps S103, S104 and S203) for changing a level of the deviation reflected into the oil control of the hydraulic chamber.
