A bearing for a motor-type fuel pump comprises a Zn—P—Ni—Sn—C—Cu-based sintered alloy and has corrosion resistance to a coarse gasoline containing sulfur or an organic acid(s); superior wear resistance; and superior conformability with a shaft as a counterpart. The bearing is suitable for use in a downsized fuel pump and has a structure in which a base comprises 3 to 13% by mass of Zn, 0.1 to 0.9% by mass of P, 10 to 21% by mass of Ni, 3 to 12% by mass of Sn, 1 to 8% by mass of C and a remainder composed of Cu and inevitable impurities. The base also comprises a solid solution phase of a Zn—Ni—Sn—Cu alloy. A Sn alloy phase containing no less than 15% by mass of Sn is formed in grain boundaries of the base. Pores have a porosity of 8 to 18% and free graphite distributed therein.
