Abstract
Provided is a friction modifier giving excellent formability in producing a friction material and capable of reducing rust formation on a rotor even when the moisture-absorbed friction material is left pressed against the rotor for a long. The friction modifier is made of a titanate compound having a tunnel crystal structure, wherein the titanate compound has a rate of chlorine ion dissolution of 0.5 ppm to 400 ppm.
