Abstract
A pump is provided having a communication portion that provides continuous communication between a pump section and a discharge section in a state where a discharge-side check valve suppresses a backflow, and a size of the communication portion is set so that, when the continuously expanding and contracting pump section contracts, a volume of gas mixed in liquid in the pump section is contracted.
