PROBLEM TO BE SOLVED: To provide a spraying device capable of producing a large amount of fine particles having a fine particle diameter capable of causing Brownian motion. SOLUTION: The spraying device of the present invention is capable of holding an atomizing tank 11 capable of storing a liquid agent, an atomizing device 12 for atomizing the liquid agent in the atomizing tank to generate fine particles, and a predetermined rotation speed. The atomization unit 10 includes a blower member and includes a blower 13 that discharges carrier air for transporting fine particles of the liquid agent into the atomization tank from a blower port 11b provided in the atomization tank. A spraying device comprising: a blowing unit 30 that blows out the generated fine particles together with the carrier air. The blowing unit 30 is formed by a substantially cylindrical blowing member 31 having a predetermined width, depth, and height, and is provided at the upper end. It has a slit-shaped spray port 32 inclined obliquely upward.
