A control apparatus of a continuously variable transmission includes a shifting controller and a detector. The continuously variable transmission includes a hydraulic pressure supplier and a continuously variable transmission unit. The continuously variable transmission unit is able to perform continuously variable shifting by a hydraulic pressure in the hydraulic pressure supplier. The shifting controller causes, when the detector detects an abnormality, the hydraulic pressure in the hydraulic pressure supplier to fall within a range that is equal to or greater than a first value and less than a second value. The first value is a value at which minimal operation performed by the continuously variable transmission unit is available. The second value is a value upon normal operation before the detector detects the abnormality.
