PROBLEM TO BE SOLVED: To provide a spiral nozzle capable of performing a uniform treatment by uniformly spreading a liquid. SOLUTION: The spiral nozzle is configured in a manner such that the liquid is jetted out in the form of droplet from a spray guide unit 1 spirally formed converging towards its center axis L. Further, the spray guide unit 1 has a liquid-contact surface 11 inclined at a predetermined angle with respect to the central axis L, such that a spreading pattern of the liquid in a plane orthogonal to the center axis L becomes a spiral-figure.
