Abstract: An aerosol spray apparatus and a method of forming a film using the aerosol spray apparatus are disclosed. The aerosol spray apparatus in accordance with an embodiment of the present invention includes: a carrier gas injection unit, which forms carrier gas by vaporizing liquefied gas and increases the pressure of the carrier gas; an aerosol forming unit, which forms an aerosol by mixing the carrier gas with powder; and a film forming unit, which sprays the aerosol in a normal pressure environment such that the film is formed on the surface of the board. The apparatus can perform a coating process with no restriction of the type and size of powder, simplify the process because the film can be formed in a normal temperature and pressure environment, and control a wide range of film thickness in a short time.
