PROBLEM TO BE SOLVED: To solve problems of conventional tube pumps: increase in the numbers of assembling operations and part items for reduction of evaporation of moisture from a tube, and increase in setting space for a plurality of tube pumps. SOLUTION: The tube pump includes at least two pump units 201A and 201B which are integrated together, each of the pump units including a tube 204; a pressing means 205 for pressing the tube 204 with rotation; and a pump case 202 housing the tube 204 and the pressing means 205 within a recessed space 203 opened at one side. The respective pump cases 202 of the two pump units 201A and 201B are fixed through a seal member 230 with the recessed spaces 203 and 203 facing to each other, so that the inside of each recessed space 203 housing the tube 204 and the pressing means 205 is substantially sealed.
