Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce a size of paint particles as compared with a case using a fan spray nozzle and reduce generation of a tail.SOLUTION: The airless coating device, which has a flow path 40 for paint 41 and comprises a nozzle 23 having an orifice 27 provided on a downstream end of the flow path 40, pressurizes the paint 41 to be sprayed from the orifice 27. In the nozzle 23, a chamber 35 is provided at a further upstream side than the orifice 27 of the flow path 40. In the nozzle 23, the pressurized paint 41 is supplied to the further upstream side than the chamber 35 of the flow path 40, and in an opening 37 at a downstream end of the device is provided a groove 36 that is connected to the chamber 35 to guide the paint 41 from the opening 37 to a direction along an inner wall surface 26a of the chamber 35.
