To provide a coated member coated with a surface coating that can greatly improve wear resistance or improve a sliding characteristic (a reduction in friction coefficient).
A coated member is formed of a base material and a surface coating which coats at least part of a surface of the base material. The surface coating is formed of TiC and columnar fine particles whose grain sizes are 1-90 nm are distributed over the outermost surface. Amorphous carbon may be included in the surface coating. The surface coating, which does not substantially include the amorphous carbon and is formed of column particles in which grain growth occurs from the outermost surface of the base material to the outermost surface of the surface coating, shows extremely high wear resistance. Such a surface coating formed of the TiC is, e.g., obtained by plasma CVD. One example of the coated member is a molding die.
