SOLUTION: This oil pump has a base part 1 having an operation chamber 11, and a rotor 3 rotatably arranged in the operation chamber 11. The base part 1 is composed of a plurality of divided bodies 13 and 18. Out of the plurality of divided bodies 13 and 18, at least one divided body 18 (a rear housing) is made of an aluminum alloy as a base material, and has a sliding opposed surface 180 having an alumite layer 185. The sliding opposed surface 180 has an alumite layer 185 of hardness Hv 500-2000 micrometer including α-alumina. COPYRIGHT: (C)2009,JPO&INPIT
