A liquid transport apparatus includes a substrate, liquid transport channels disposed on a surface of the substrate in which a conductive liquid is transported, electrodes disposed in regions in corresponding ones of the liquid transport channels, and wiring portions coupled to corresponding electrodes and extending along the surface of the substrate between adjacent liquid transport channels. Also, the apparatus includes an insulating layer which is disposed so as to cover the electrodes. The insulating layer has a surface in which the liquid repellency changes according to an electrical potential difference between the conductive liquid and the electrodes. The apparatus also has a potential applying unit which applies an electric potential to each of the electrodes through terminals at the ends of the wiring portions.
