<p>PROBLEM TO BE SOLVED: To provide a method of efficiently manufacturing an exterior part for timepiece with superior aesthetic appearance as a method which less wastes materials and is small in load on environment.SOLUTION: A method of manufacturing an exterior part 10 for timepiece includes a film forming process of forming a film P3 with impact force of aerosol by blowing the aerosol, formed by dispersing particles P31 in air, to a base material P1 from a nozzle through a mask P6 having an opening part P61. A constituent material of the base material P1 has a transparency of 85% or higher in light transmissivity. As a constituent material of the mask P6, various resin material including metal materials are used. The mask P6 has a sectional area increasing part where the opening part P61 increases in sectional area from the surface opposed to the base material P1 to the opposite surface.</p> |
