PROBLEM TO BE SOLVED: To provide a control device of a negative pressure pump for a brake, accumulating the negative pressure required for a negative pressure chamber without operating a negative pressure pump to excess. SOLUTION: An EGI_ECU 50 determines whether or not a vehicle experiences running above a preset creep vehicle speed after an engine is started. The EGI_ECU 50 inhibits the operation of the negative pressure pump 40 before the vehicle experiences running above the creep vehicle speed. Thus, in the state where clearly a large braking force is not needed such as the stop state immediately after the engine start, the operation of the negative pressure pump 40 can be inhibited so that unnecessary drive of the negative pressure pump 40 can be precisely prevented.
