PROBLEM TO BE SOLVED: To equalize a spray quantity in a width direction while expanding the spraying angle in the width direction perpendicular to a longitudinal direction in a nozzle having a wide spraying angle in the longitudinal direction. SOLUTION: A flowing-in passage is installed from a flowing-in opening at one end toward a spraying side at the other end along the center axis line of a nozzle body, and a pair of main holes with a top end of a circular arc shape are installed at the tip of the spraying side of the flowing-in passage on both sides in a width direction of the center of the nozzle body, while a wide cut groove in a direction perpendicular to the width direction and in a diameter direction passing through the center of the nozzle body is installed on the flat top surface of the spraying side of the nozzle body, the cut groove is tilted toward the center in a depth direction from both ends of the longitudinal direction, a pair of spraying openings communicating with the pair of main holes are installed close to the width direction, and the cross section in the width direction of the cut groove is made to be of a trapezoid shape by tilting both side walls in the width direction of the cut groove in the direction close to the top surface.
