A pump channel extending from a suction port to a first discharge port is formed inside the pump body. The pump channel includes a suction path, an impeller channel which is formed inside the impeller and into which liquid in the suction path is introduced, a volute portion which is formed on a radially outer side of the impeller and into which liquid in the impeller channel is introduced, and a discharge path into which liquid in the volute portion is introduced. A liquid separation reduction structure that reduces separation of liquid flowing in the pump channel is provided in the pump channel.
