Patent ID: 8596763

Claim:
A liquid transport apparatus comprising: a substrate having a planar insulating surface; a plurality of liquid transport channels disposed on the planar insulating surface of the substrate and in each of which a conductive liquid is transported; a plurality of electrodes having a surface contacting and disposed on the planar insulating surface of the substrate in regions corresponding to respective ones of the liquid transport channels; a plurality of wiring portions each having a terminal at an end thereof, and each wiring portion coupled to the surface of a corresponding one of the electrodes and extending from the surface along the planar insulating surface of the substrate between adjacent liquid transport channels to the terminal; an insulating layer, which is disposed so as to cover the plurality of electrodes, having a surface in which the liquid repellency changes according to an electrical potential difference between the conductive liquid and the electrodes; and a potential applying unit which applies an electric potential to each of the plurality of electrodes through each terminal provided on the plurality of wiring portions.
