PROBLEM TO BE SOLVED: To provide a nanoparticle-containing slurry spraying device where generated mist has a uniform particle diameter, misty spraying can be achieved so as to be uniformly distributed and the particle diameter of the mist can be controlled and to provide a spray coating device with the spraying device.SOLUTION: A nanoparticle-containing slurry spraying device comprises: an ejection part 20 to eject a spray medium from the tip of a spray nozzle 21 through the inside of a supply pipe 22; and a slurry supply part 30 to supply a nanoparticle-containing slurry W into the spray nozzle 21 through through openings 20a formed with the spray nozzle 21 and a nozzle guide 23. A plurality of the through openings 20a having the same sizes are formed and positioned at equal intervals in the circumferential direction of a nozzle part. The opening area of the through openings 20a is expandable and contractable. |
