A fan-spray nozzle capable of preventing generation of tailing and improving spraying of paint, as well as being readily manufactured. In the nozzle, a through-hole of a cylindrical section is formed so as to have a cross-sectional area larger than that of a hemispherical depression formed in a dome section and at a front end thereof into a substantially elliptical or oval shape in cross section. The oval-shape has a minor axis portion formed so as to have a length equal to the diameter of the depression so that the through-hole may be smoothly connected to the hemispherical depression at the minor axis portion. The semicircular groove is formed so as to extend in a direction substantially perpendicular to the minor axis portion of the oval shape and is also formed so as to have a bottom which is formed into an acute shape and terminates at substantially the same level as a step formed between a major axis portion of the oval-shaped cross section of the front end of the through-hole and the depression or thereabove.
