A fluid transport device transports fluid containing electrolytes within a flow channel. At least a portion of the inner walls of the flow channels are hydrophilic from the inlet to the outlet thereof except at at least one valve portion. The device also includes: the valve portions, which are hydrophobic and function to block transport of at least one fluid; electrodes, which are provided at the at least one valve portion and function to reduce the surface tension of the fluid; and air vents, which are provided at the at least one valve portion and function to introduce air in order to block the fluid.
