Abstract: Provided is a method for manufacturing a hard carbon-based coating. The method includes: a step A of preparing a film-forming apparatus including a power supply device and a discharge electrode containing a carbon material, and a substrate having a surface on which a coating is to be formed; and a step B of causing the film-forming apparatus to repeatedly generate a discharge between the discharge electrode and the substrate, to form a hard carbon-based coating on the surface.
