Claim:
1. A control device for a continuously variable transmission, comprising: a continuously variable transmission in which a belt is wound around a primary pulley and a secondary pulley to transmit power; a clutch that is provided between a drive source and the primary pulley and cancels or generates a power transmission state; a primary pulley rotational speed sensor for detecting a rotational speed of the primary pulley; a stopped state detection unit for detecting whether a vehicle is in a stopped state; a belt slippage detection unit for detecting belt slippage on the basis of a signal of the primary pulley rotational speed sensor; and a prohibition unit for prohibiting detection of the belt slippage by the belt slippage detection unit in a case where a neutral range is selected by a shift lever operation by a driver and the vehicle is in the stopped state wherein, in a case where the vehicle is not in the stopped state even when the neutral range is selected, the belt slippage is detected by the belt slippage detection unit.
