Beschreibung
Zusammenfassung:	This metal material for a sliding contact has a substrate formed from copper or a copper alloy, and a Pd-containing layer that is formed as an outermost layer on at least one part of the substrate and that contains 95 mass% or more of Pd, the metal material being characterized in that, in the Pd-containing layer, the crystal orientation rate of a (111) plane as measured by X-ray diffraction is greater than 60%, and the total of the crystal orientation rate of a (200) plane and the crystal orientation rate of a (220) plane is less than 40%, the metal material for a sliding contact being exceptional in terms of wear resistance while also having sufficient electroconductivity to conduct electricity to a motor coil. Also provided are a brush member for a motor, and a vibration motor, in which the metal material for a sliding contact is used.
