Provided is a novel sintered bearing superior to conventional ones in a wear resistance. The sintered bearing has a structure in which Ni-P alloy particles having an average diameter of 10 to 100 µm are dispersed in an amount of 1 to 20% by mass in a Cu-Ni-based sintered alloy base. The Cu-Ni-based sintered alloy base contains 20 to 40% by mass of Ni, 0.1 to 1.0% by mass of P; or contains 10 to 25% by mass of Ni, 10 to 25% by mass of Zn and 0.1 to 1.0% by mass of P. |
