Abstract
Provided is an alkali metal titanate which, when used as a constituent material of a friction material, is excellent in heat resistance and friction force and capable of effectively suppressing wear of a mating material disposed to face the friction material. The alkali metal titanate includes a sodium atom and a silicon atom. The content of the sodium atom is 2.0 to 8.5 mass %. The content of the silicon atom is 0.2 to 2.5 mass %. The ratio of the content of an alkali metal atom other than the sodium atom to the content of the sodium atom is 0 to 6.
