A friction material comprises a base and a porous friction generating layer penetrating into and integral with the base. The base presents a bonding surface. The porous friction generating layer presents a friction generating surface facing opposite the bonding surface of the base. The porous friction generating layer comprises fibers and friction adjusting particles, and about 30 to about 95% of a total surface area of the fibers is in contact with the friction adjusting particles. A curable resin is dispersed throughout the porous friction generating layer and the base.
