PROBLEM TO BE SOLVED: To provide a clutch control device of a hybrid car, which corrects characteristics in a half-clutch state, and preventing an engine start failure due to drawing of driving force at the start of engine or insufficient cranking torque. SOLUTION: A hybrid car is configured by serially connecting an engine Eng, a first clutch CL1, and a motor generator MG. The clutch control device of the hybrid car includes an integral controller 10 for commanding motor rotation and target clutch torque to a fixed value, and for, after the clutch torque reaches the fixed value, until engine rotation synchronizes with motor rotation, correcting the target clutch torque based on a difference between the target clutch torque and motor torque.
