Abstract:
1. A liquid transporting apparatus which transports an electroconductive liquid, comprising: a channel forming body having a liquid channel through which the liquid flows formed therein; a transporting electrode arranged on a surface, of the channel forming body, defining the liquid channel; an insulating layer arranged on the surface of the channel forming body defining the liquid channel to cover the transporting electrode; a power supply which applies a predetermined electric potential to the transporting electrode; and a temperature regulator which regulates a temperature of the liquid in the liquid channel at a predetermined temperature; wherein the liquid channel has a common liquid chamber and a plurality of individual channels which are branched from the common liquid chamber; wherein the transporting electrode has a plurality of individual transporting electrodes corresponding to the individual channels; wherein the temperature regulator has a plurality of heating spots corresponding to the individual transporting electrodes; wherein the temperature regulator includes a heater which heats the liquid in the liquid channel; wherein the heater is a heat generator which releases heat by an electric current; wherein the heat generator is formed on the surface of the liquid channel on which the transporting electrode is arranged; and wherein the insulating layer which covers the transporting electrode covers the heat generator.
