An axially sliding contact type of a commutator which is capable of removing the problem related to a braking loose caused by magnetic force to prevent increase of consumed electricity, has a rotor including the commutator, and an electric motor having the rotor, in which a gap is axially formed. The commutator is of an axially contact type and comprises a plurality of metal plates made of copper and a noble metal layer coated on the metal plates in a state of disposing a separate layer between the metal plates and the noble metal layer.
