    Abstract: A tube pump and a fluid delivery method, the tube pump including a plurality of pressing portions and a tube that delivers fluid. The pressing portions is spaced apart from each other in a rotational direction and provided for a rotation body turned by a drive unit and the tube is provided on an outer circumferential side of the rotation body. The tube pump includes a control unit that turns the rotation body opposite to a delivery direction until the rotation body reaches a predetermined angle so as to restore an area of the tube, pressed by the pressing portion on a most upstream side in the delivery direction, by an increase in pressure within the tube accompanied with a movement opposite to the delivery direction of the pressing portion adjacent to a downstream side in the delivery direction.
