PROBLEM TO BE SOLVED: To provide a tube pump and a fluid delivery method using the tube pump, capable of stably controlling delivery of a fluid while simplifying a structure.SOLUTION: In a tube pump 1 in which a plurality of pressing portions 18, 18 are disposed at intervals in a rotating direction, on a rotor 15 rotated by a driving portion 19, and a tube 20 for delivering a fluid is disposed at an outer peripheral side of the rotor, a control portion 26 is disposed to rotate the rotor to an anti-delivery side at a prescribed angle so that a region 21 crushed by the pressing portion 18A at the most upstream side in a delivery direction of the tube, is recovered by pressure rise in the tube in accompany with movement to an anti-delivery side of the pressing portion 18B adjacent at a downstream side in the delivery direction. |
