Abstract
Provided is a friction member (such as a disc brake pad) having light weight by reducing weight of a back plate and having improved durability after repeated braking. The friction member is specifically a friction member in which a friction material (overlying material) is disposed through an underlying material on one surface of a back plate comprising a material having a lower specific gravity than that of steel, wherein the underlying material comprises 30 mass % or more in total of a bonding material, an organic filler, and an organic fiber.
