PROBLEM TO BE SOLVED: To provide a cooling control device of an electric vehicle which is convenient and unfailingly removes air bubbles.SOLUTION: A cooling control device of an electric vehicle includes: a travel device 2 including an electric motor 5 which outputs a driving force for traveling; a cooling device 3 which stores a coolant for cooling the travel device and is connected with the travel device; and a controller 4 which changes a circulation speed of the coolant flowing in the cooling device. The controller includes: a cooling control section 18 which changes the circulation speed of the coolant according to a temperature of the travel device; an operation detection section which detects a predetermined operation conducted by an occupant; and an air bubble control section 20 which controls the coolant so that its circulation speed becomes faster than the circulation speed set by the cooling control section 18 when the predetermined operation is detected.
