Abstract
In this pump apparatus, each of plural gate marks formed in a second blade member is formed at an intermediate position in a circumferential direction of a rotor between two blades that are adjacent to each other in the circumferential direction of the rotor, and the even number of blades are disposed between the gate marks in the circumferential direction of the rotor. The plural gate marks are disposed on an outer side, in the radial direction of the rotor, of an outer circumferential surface of a portion, which is connected to the second blade member, in a magnet holding member formed in a tubular shape.
