ABSTRACT:
An object such as an automobile part, an image forming apparatus part, a bicycle part, other machine parts, a sport article or its part, a toy or its part, or a rain article or its part has a portion to be in contact with a contact object. The contact portion is made of at least one kind of material selected from a group including polymer material such as resin or rubber as well as glass, and the contact portion has a surface entirely or partially coated with a carbon film (typically, a DLC film) having a wear resistance as well as at least one of a lubricity, a water repellency and a gas barrier property. The carbon film is formed on the object with a good adhesion.
