The invention relates to an idling stop control device of a vehicle. The control device starts an execution of a decompression control at an engine-speed-decreasing-period timing within an engine-speed-decreasing period when an inclination gradient is a downward slope gradient smaller than a predetermined gradient. The period corresponds to a period between a timing when the engine speed reaches a peak engine speed after the engine speed exceeds a complete explosion engine speed after the execution of the engine restart process is started and a timing when the engine speed decreases to a stable idling engine speed. On the other hand, the control device starts the execution of the decompression control at a complete-explosion-achievement timing when the inclination gradient is a downward slope gradient equal to or larger than the predetermined gradient.
