PROBLEM TO BE SOLVED: To appropriately control a negative ion supply amount in order to obtain a desired engine output. SOLUTION: This negative ion supply control device for controlling the negative ion supply amount V supplied to an intake passage of an internal combustion engine detects a combustion state in a cylinder, and feedback controls the negative ion supply amount so that the detected combustion state approaches a target combustion state. Concretely, the negative ion supply amount V is feedback controlled based on a deviationΔθmax between a predetermined target crank angleθmaxtrg and a crank angleθmax that cylinder inner pressure Pc detected by a cylinder inner pressure sensor is maximized.
