To prevent the distortion of a tube and thus prevent the flotation of the tube when mounting the tube on a pump unit by applying a linear marking to the side wall of the tube.
This tube pump comprises a pump frame having a tube supporting face for circularly restricting the outer shape of the tube so that the tube is arranged along the supporting face, a pump wheel to be rotated with the driving force of a driving means, and a roller supported on the pump wheel so as to be movable between a first position on the rotation axial center side of the pump wheel and a second position apart from the rotation axial center. It also has a tube holding member for holding the tube at a high position from the bottom face of the pump frame. The tube holding member holds the tube toward the bottom face of the pump frame. The linear marking is applied to the side wall of the tube in the longitudinal direction for discriminating whether the tube is assembled on the pump frame in a twisted condition, or not.
