Abstract
Provided axe porous titanate compound particles capable of giving excellent fade resistance when used in a friction material, a resin compound and a friction material each containing the porous titanate compound particles, and a method for producing the porous titanate compound particles. Porous titanate compound particles are each formed of titanate compound crystal grains bonded together and have a cumulative pore volume of 5% or more within a pore diameter range of 0.01 to 1.0 μm.
