PROBLEM TO BE SOLVED: To provide an adhesion preventive application apparatus for sheet materials without lowering of the agitating effect even when discharge of agitating air is stopped for a long time. SOLUTION: The adhesion preventive application apparatus includes two or more air discharging tubes 30 agitating an aqueous solution B of an adhesive preventive by discharging air into a tank 10 of the adhesion preventive agent from the lower end of each tube 30, and air is discharged from individual air discharging tubes 30 toward the bottom surface of the adhesion preventive agent tank 10, resulting in the capability of agitating the aqueous solution B of the adhesion preventive agent thoroughly including the bottom-surface part of the adhesion preventive agent tank 10. Since the lower ends of individual air discharging tubes 30 are opened toward the bottom surface of the adhesion preventive agent tank 10, the adhesion preventive agent precipitated never invades individual air discharging tubes 30 even when the supply of the air is stopped for a long time, leading to reliable prevention of clogging of individual air discharging tubes 30 by the precipitated adhesion preventive agent.
