Liquid Droplet Transport Apparatus

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.
