PURPOSE: A water-film type nozzle apparatus is provided to control flow rate according to injecting angle, thereby selectively forming water-film for long time in areas where fire-extinguishing solution is required. CONSTITUTION: A water-film type nozzle apparatus comprises a nozzle body(10) and a rotation body(20). The nozzle body comprises main body flow paths(13) and a rotator bonding groove. In the nozzle body, a first main body flow path(13a) is connected with an inlet port in which extinguishing liquid of the high pressure flows in. A plurality of second main body flow paths(13b) is connected with a first main body and is arranged for a plurality of vents to be branched to width direction. A rotator bonding groove is formed in a junction between the first main body flow path and the second main body flow path.
