Beschreibung
Zusammenfassung:	The present invention relates to a friction member comprising a friction material and a back metal, wherein the friction material comprises no copper, or has a copper content of less than 0.5% by mass in terms of a copper element even if the friction material comprises copper, the friction material comprises magnesium oxide and a carbon material comprising graphite and coke, the carbon material is obtained by blending in a combination of a coarse-grained material and a fine-grained material, an average particle diameter of the coarse-grained material is 100 to 600 μm, and an average particle diameter of the fine-grained material is less than 100 μm.
