PROBLEM TO BE SOLVED: To apply a constant amount of an adhesive always uniformly in a constant width by forming the tip part of a nozzle in the shape of a wedge so that the thickness is decreased gradually toward a discharge opening for the adhesive and saw tooth-shaped projections comprising numbers of notches on the upper side projecting from the lower side of the discharge opening. SOLUTION: In a nozzle body 7, a chamber 9 in the shape of a longitudinally long cone or a wedge for housing an adhesive is disposed in its inside, an inflow opening 10 for introducing the adhesive is formed in the lower surface of the chamber 9, and threads 12 for fixing a cartridge container are formed around the opening 10. Comb tooth-shaped projections 8 are formed in one side part in the tip of the nozzle body 7. The adhesive is discharged from the body 7 by extruding an extrusion gun, when the adhesive is applied on a prescribed plane, irrespective of the degree of skill of an operator, a constant amount of the adhesive is applied always uniformly in a constant width. Accordingly, the adhesive can be applied uniformly on a wide plane such as a floor surface, eliminating problems such as the shortage of an adhesion area.
