A method of forming an oxide film 3 on a surface of a base material 12 constituted from an inorganic material is disclosed. The oxide film 3 is constituted from a material containing an oxide of the inorganic material as a major component thereof. The method includes the steps of: preparing the base material 12; supplying a process liquid containing alcohol onto the surface of the base material 12 to form a liquid film 2 of the process liquid thereon; producing an oxide of the inorganic material through a reaction of the inorganic material with the alcohol in the liquid film 2; and eliminating the process liquid remaining in the liquid film 2 to form the oxide film 3 on the surface of the base material 12. Further, the oxide film 3 described above, a component including the oxide film 3, and an electronic apparatus including the component are disclosed.
