Abstract:
1. A liquid transporting apparatus which transports an electroconductive liquid, comprising: a substrate having an insulating surface; a plurality of liquid transporting channels which transport individually the electroconductive liquid and which are arranged at intervals on a plurality of first areas of the insulating surface, respectively, the first areas defining the liquid transporting channels; a common liquid chamber which communicates with the liquid transporting channels, and which supplies the electroconductive liquid to the liquid transporting channels; a plurality of individual electrodes arranged on the first areas of the insulating surface respectively; an insulating layer which covers the individual electrodes, and in which a liquid repellent property of a surface thereof changes depending on an electric potential difference between the electroconductive liquid and the individual electrode; a plurality of wire portions which are arranged on the insulating surface, and which are connected to the individual electrodes respectively; and a driver IC which is arranged on the insulating surface and which is connected to the wire portions, and which applies a driving electric potential to the individual electrodes via the wire portions; wherein the wire portions make a thermoconductive contact with the driver IC and the electroconductive liquid.
