Abstract
The problems in accordance with the present invention are: to provide a DLC film, wherein a protective film having a segmented shape is easily formed, quality control of the protective film is improved, segmented shapes with a high degree of freedom (that are complicated) are possible, and the application of the DLC film is possible not only to two-dimensional shapes but also to three-dimensional shapes; and to provide a method for forming the DLC film. As solutions to the problems, there are provided a protective film and a method for producing the protective film, characterized by, when forming on a substrate the protective film having a segmented shape formed by depositing a film so that the film is formed divided into segments, masking the substrate using a drawing material so that segments having predetermined shapes are obtained, thereafter depositing the protective film, and then removing the masked part to form a spacing between segments.
