    Abstract: Provided is a pump for supplying a liquid. The pump includes: a tube including a pump chamber communicating with a chemical liquid inlet and a chemical liquid outlet, and configured to discharge a chemical liquid through a change in volume due to contraction and expansion; and a driving unit contracting or expanding the tube in a longitudinal direction, in which the tube includes: a flexible tube body including a pump chamber which has an increased internal volume when is contracted in a longitudinal direction and has a decreased internal volume when is expanded in the longitudinal direction, and which has a jar shape of which a radius is increased from the chemical liquid inlet to a center of the pump chamber, and the radius is decreased from the pump chamber to the chemical liquid outlet; a first flange provided at one end of the tube body and including the chemical liquid inlet; and a second flange provided at the other end of the tube body and including the chemical liquid outlet.
