The invention provides a pump. This pump is provided with: a rotor that can rotate about a central axis; a stator located on a radial outer side of the rotor and surrounding the rotor; a pump part connected to one side of the rotor in the axial direction; a support member having a rotor housing part located on the inside in the radial direction of the stator and housing the rotor therein; a motor housing surrounding the stator, the rotor, and the rotor housing portion from the outside in the radial direction; and a pump cover positioned on one side of the motor housing and the support member in the axial direction and covering the pump portion. The pump cover has an annular first contact surface. The motor housing has a second contact surface in contact with the first contact surface. The support member has a third contact surface in contact with the first contact surface. The first contact surface is welded to the second contact surface and the third contact surface. 本发明提供泵。该泵具有：转子，其能够以中心轴线为中心进行旋转；定子，其位于转子的径
