PROBLEM TO BE SOLVED: To enhance characteristics of a film by increasing the density of a layer formed by the deposition of a powder of a film material by irradiating the film material with a laser beam without giving an influence on a substrate. SOLUTION: In a method for forming the film by a cold spray method, which forms the film of the film material on the substrate K by jetting a powder of the film material to the substrate K from a spray nozzle 7 together with an orifice gas whose temperature is lower than a melting point temperature of the film material, this film-forming method includes irradiating a path of the powder of the film material, which reaches from the spray nozzle K to the substrate, with the laser beam for heating the powder, using a laser irradiation device 10.
