Beschreibung
Zusammenfassung:	Provided is a sintered bearing (1, 2) for a fuel pump, including raw material powder including 8.5% by weight to 10% by weight of aluminum, 0.1% by weight to 0.6% by weight of phosphorus, and the balance including copper as a main component, and inevitable impurities. The sintered bearing (1, 2) has a structure of a sintered aluminum-copper alloy, and has a pore formed in a surface layer portion of the sintered bearing, which is smaller in size than an internal pore of the sintered bearing.
