PURPOSE: A nozzle for spraying a liquid phase material is provided which coats a flat plate to a certain thickness during fluid spraying by forming a slit formed on the nozzle so that the width of the center part of the slit is different from that of the outer part of the slit. CONSTITUTION: In a spray gun comprising a connecting tube which is connected so that sealant of the outside is flown in by pressure of a pump; a circular conduit which is connected to the connecting tube so that the sealant supplied through the connecting tube is sprayed to the outside; a rod which is moved up and down with inserted into the circular conduit so as to spray or block the sealant to the outside; a hydraulic piston moving the rod up and down with coupled to the upper part of the rod; and a valve sheet opened or closed according to the vertical movement of the rod, the nozzle (200) for spraying a liquid phase material comprises a flange (210) coupled to the lower part of the valve sheet of the spray gun with a cap nut; a cylindrical body (220) which is formed on the flange (210) in a cylinder form and guides sealant so that the sealant is come into a position where it is sprayed to the outside; and a slit (230) the width of which is narrowed, thus has a different shape in the direction from the center to the length directions of both sides so that the sealant is uniformly sprayed onto the outer part of the flat plate while it is formed in a V shape with traversed along the upper center of the cylindrical body (220).
