A pump equipped with: a molded stator having a substrate on which a magnetic pole position detection element has been mounted,and a rotor having a rotor part one axial end of which opposes the magnetic pole position detection element and the other axial end of which is provided with an impeller attachment part. The rotor part is equipped with: a magnet,a sleeve bearing,and a resin part, which is formed of a thermoplastic resin used in the integral molding of the magnet and the sleeve bearing, and which forms the impeller attachment part. The magnet is equipped with multiple through-holes extending in the axial direction, and the multiple through-holes are filled with thermoplastic resin that forms a portion of the resin part.
