Abstract: A friction material for a brake pad comprises a fibrous base material without a metal fiber, and comprises a binder and a friction modifier. The friction material comprises 0.3% to 2.0% by weight, relative to the entire friction material, of a non-crosslinkable polyolefin having a melting point higher than the melting temperature of the binder. The friction material can suppress increase in friction coefficient of a friction material during initial brake operation and reduce the occurrence of abnormal effects and squealing in low-temperature and high-humidity environments.
