PROBLEM TO BE SOLVED: To provide a tube pump with a tube easy to mount/demount, wherein the pulsation of fluid is greatly reduced by constantly delivering fluid through the tube at all times. SOLUTION: The tube pump comprises the tube 20 to be a transportation passage for the internal fluid, a screw-shaped core 30 arranged with a rotating center shaft parallel to the tube 20 for delivering the fluid through the tube 20 while pushing the tube 20 down, a flexible skin 32 covering the core 30, and a drive mechanism 40 for rotationally driving the core 30. In this case, lubricant is filled in a gap between the core 30 and the flexible skin 32 covering the core 30. This lubricant filling construction reduces the friction of the skin 32 against the core 30, smoothes the delivery of the fluid through the tube 20 and improves the durability of the skin 32.
