NOVELTY - The apparatus (1) has a film formation chamber (105) arranged with substrate (115). A nozzle (10) injects the mixing phase of gas and nanoparticle towards the substrate. A laser irradiation unit irradiates the laser beam (112) to target (107) so that a nozzle inlet is located on extended line of plume containing the emitted nanoparticle such as metal and ceramic nanoparticles from target surface. A gas injection unit injects the gas towards the nozzle inlet along long axis of plume so that the several flow paths for flow of combined gas collide.    USE - Laser ablation film-forming apparatus. Uses include but are not limited to film such as insulating film of electrostatic chuck, electrostatic motor, heat radiation substrate for electronic device, vacuum device, plasma-resistant semiconductor device, flat panel, electrically conductive film, transparent film, wear-resistance film, dielectric film, piezoelectric material film, pyroelectric material film, photocatalyst film, heat ray reflection film for micro electro-mechanical system (MEMS) manufacturing apparatus, metal mold, piezoelectric device such as capacitor and piezoelectric actuator, oxygen gas sensor, heat resistant film for polycrystalline solar cell, dye-sensitized solar cell and semiconductor element, and anti-reflective film, UV absorption film, water-repellent element, hydrophilic element, engine, turbine, artificial bone and dental implant.    ADVANTAGE - The efficiency for conveying nanoparticle discharged from target surface through nozzle inlet can be improved. The possibility that the discharge of nanoparticle in direction perpendicular to major axis direction of plume, can be suppressed effectively and the possibility for adhesion of nanoparticle to nozzle inlet can be suppressed.
