ABSTRACT:
A liquid conveying substrate comprises: rectangular electrodes which are disposed on the substrate surface and whose surfaces are covered with a dielectric with a water repellent surface; first axial electrode columns where the rectangular electrodes are coupled in an x direction; and second axial electrode columns where the rectangular electrodes are coupled in a y direction. Accordingly, electrodes necessary for conveying liquid droplets can be arranged on one substrate, and the number of mechanisms for controlling the potential can be suppressed.
