PROBLEM TO BE SOLVED: To provide a tube pump with a tube having improved durability. SOLUTION: The tube pump 10 comprises an approximately U-shaped pump frame 16, the flexible tube 14 arranged in the pump frame so as to be approximately U-shaped along the inner wall of the pump frame, a pump wheel 18 rotatably arranged in the pump frame adjacent to the tube, a first roller 20 arranged on the outer periphery side of the pump wheel and having a first outer diameter, and a second roller 22 arranged at a position different from a position where the first roller is arranged on the outer periphery side of the pump wheel and having a second outer diameter smaller than the first outer diameter. With the rotation of the pump wheel, the first roller crushes the tube arranged in the pump frame to transfer liquid in the tube and the second roller suppresses the movement of the tube in the pump frame.
