Abstract
A sintered friction material includes a copper component in an amount of 0.5% by mass or less, a titanate as a matrix, a ceramic material, and a lubricant. A method for manufacturing a sintered friction material includes a step of mixing raw materials including a titanate for forming a matrix, a step of molding the raw materials, and a step of sintering a molded body molded in the molding step. In the method, a sintering temperature in the sintering step is 900° C. to 1300° C.
