To provide a coated member which is suitably used for a tool, a die, a sliding component or the like and can improve durability even if lubricating oil considering environments is used, and to provide a method for working a metallic material performed using the coated member as a tool or a die.
The coated member 10 is used in the presence of lubricating oil 20 obtained by blending lubricating base oil with a hydrocarbon based additive 21 composed of one or more carbon atoms in which at least one kind selected form an amino group, a carboxyl group, a hydroxy group and a carboxylic ester group is bonded, and includes: a base material 11; and a hard amorphous carbon film 12 composed of silicon, formed on the surface of the base material 11 and slid with a mating material. When the covered member 10 is a tool or a die, the lubricating oil 20 obtained by being blended with the hydrocarbon based additive 21 is fed to a space between the sliding face of a metallic material and the sliding face of the tool or die, and the metallic material is worked.
