PROBLEM TO BE SOLVED: To provide a control device for a continuously variable transmission capable of effectively reducing shift hunting in the continuously variable transmission to reduce deterioration of responsiveness after the shift hunting ends. SOLUTION: In the case wherein a shift hunting detection means S2 detects a shift hunting based on a switching period or a switching frequency of up-shift and down-shift, a correction quantity computing means S3 computes the correction quantity of a learning instruction value, and a learning instruction value correcting means S4 decides a Duty value of a solenoid valve based on the in-hunting learning instruction value obtained by correcting the learning instruction value by the correction quantity. In the case wherein the shift hunting detecting means detects that the shift hunting ends, a reset means S7 switches an instruction value for controlling the solenoid valve or the like from the in-hunting learning instruction value to the learning instruction value.
